  1. I was wondering what a good swap would be. I have the stock 5.3 but I want some umph. I travel for work and still need gas mileage but I have hit a dead end in research. Can anyone help me?
  2. Hey folks, first time posting here and maybe it’s a common thing. I’ve searched google and YouTube for days, replaced parts, and done the troubleshooting I know to do. So here it is, bear in mind, im no auto mechanic. I’m a jet mechanic/toolmaker. Lol my front pass brake locked up Friday, and the abs/parking brake light has been on since the dealer I got the truck from replaced the parking brake cable. I don’t hear a roaring, so I don’t feel like it’s a hub, but I do have some bouncing on the front end which leads me to think it may be an axel, which I still have to get looked at. parking brake and abs lights come on after a few seconds of driving, I hear brakes grinding, and I just replaced both front rotors, pads, and passenger caliper and abs sensor after it locked up; since it melted the abs sensor cable. brakes are bled properly and working, but they aren’t fully releasing. I’ve checked fluid, it’s not overfilled. Driver hub was previously replaced but not passenger for some reason. I considered ordering a hub for the passenger side just for that. Rotors are 305mm and the pads I installed are ceramic from brake best. Yes, the rotors get hot after a short drive, like too hot to touch. I’d rather not have these things lock up on me again. The only thing left I know to check are the piston in the master cylinder, or the passenger hub. Any ideas? If I’ve missed good reference material or prior posts please feel free to comment with a link and a nice “check here dumbass.” Lol thanks in advance.
  3. Hey guys I’m new to the forum as well the brand. I recently just bought a 2019 custom trail boss which only offers the 5.3. I wanted the 6.2 but that came with only the higher trims. I’m familiar with the 5.7 hemi and I’m kinda down about the 355 horsepower/ 383 torque compared to my hemi that I traded. What can I do exactly to get more power to the engine?
  4. Newb here. My 07 Yukon has been in the shop over a week now. (Local mechanic) Have had the vehicle about a year, changed the oil regularly, replaced oil sensor and sending unit due to the infamous low oil pressure warnings. Thing has driven great until randomly one day she started idle hard and misfired when going into first. I changed all sparks, plugs. No change. Shop is saying my oil pump is completely shot..? I've had no noise no other signs of it starting to fail. My sensor would routinely go off a month prior to oil change being due. Do these things really just crap out? Could it be related to my misfire? They are checkin the head on that, otherwise she drove normal and smooth once I go over 15mph. If she survives and my wallet doesn't get drained, I will be disabling the AFM.
  5. So I have a 04 Silverado crew cab z71 4wd. I have a 2.5 inch lift, cold air intake, and 285/70/17 mud tires. I’m looking to turn my truck into a little bit more of a power house. I plan on getting all new spark plugs (need help with which spark plugs) and a whole new exhaust from the headers back. (Also need help finding that). I’m trying to get the most performance out of these upgrades as I can as I am getting a inTune i3 8245 Platinum + Custom DiabLew Tune as soon as I decide what spark plugs, and full exhaust system I plan on getting. I want the most performance I can get out of these upgrades.
  6. I just bought a 2015 GMC Sierra Double Cab 2WD 5.3L and I'm trying to find a full headers back exhaust system. If it helps any to tell what i like, I like the sound of my dads F150 5.0L with long tube headers and mbrp exhaust. I like loud but not obnoxiously loud. I like a nice sound of a V8.

  8. So I had a check engine light on for awhile didnt think much of it till it thru me into limp mode before work one morning. I did some digging around and ended up replacing my throttle body. Light went away everything was great then a week later it came back on and not long after that it thru me into limp mode. It hasnt done it since. The truck is throwing codes for the TPS, Evap, and a random misfire. Before i go spending money I dont have and throwing random parts at it does anybody have any clue? its been several days since it put me in limp mode but it hasnt come back yet.
  9. Selling my personal truck this spring as it just sits and never gets used now that I drive a company truck. Hate to see it go as I love the truck but It just doesn't make sense to keep it.

Lots more pictures available, this is all a am able to post due to file size. Any questions or interest shoot me a PM and I can provide my phone number.
  10. Howdy! New to the forum, not sure if I’m doing this right. Anyhow, I’d like to install true duals with an X pipe on my Silverado. It’s a 2002 1500 Extended cab with the 5.3L. Is there a bolt on exhaust system like the one I’m looking for, or would I need to have it custom built and fit at a shop? If I need to have it built, is there a good exhaust shop in Western Kentucky you could recommend? Thank you!
  11. I've owned my 2019 RST Z71 crew for about a month now. In as much time, I've started to get a firm feel for what I like and do not like about the truck. I thought I would share my thoughts here... but take them for what they're worth! A little background... I drive a whopping 8,000-10,000 miles per year, due to my job having me out of town a lot. 70% of my driving is city driving, and my daily commute is about a 14 mile round trip on suburban 45mph roads with stoplights. I upgraded to the 2019 RST from a 2007 LT2 Texas Edition Silverado Crew RWD, which I put about 110K miles on after buying it used in 2009. I researched a new truck for about 3-4 months. I looked heavily at the F-150, as well as certified and new 2017/2018 Silverados and Sierras. I've driven Chevys since 2001, but I really consider myself brand agnostic, looking for the best product on the market for my needs at the best price. My budget was pretty flexible, but I wanted something $45K or less. After visiting a good friend of mine, who owns a Chevy dealership in West TX, I realized I did not want a K2 Silverado. This reduced my decision to a 2019 Silverado or a 2018/2019 F-150. Ultimately, I felt the better value was in the 2019 Silverado, and I ended up liking the truck more than what I was finding in the F-150. I went with the RST, as I'm very over the chrome look. I think the monochrome appearance looks way more "modern", and I just generally liked it more. I didn't need a 2" lift and aggressive tires, so I passed on a Trail Boss. I do, however, LOVE the black front ends and wheels on them. My RST MRSP was $53,800. I got All Star + Convenience II, Z71 packages, etc. A similarly optioned 2019 F-150 was around $61K. Sheesh. I paid $43,660 for it + TTL, etc. The only other option I could have added was Safety I. Because there were only 3 Satin Steel RSTs with the options I wanted within 500 miles of me, I sacrificed Safety I... but I don't really miss it. I like having the corner blind spot mirrors vs. the blind spot indicators, etc. First, let me start with some of the things I do not like... Trim options missing. I realize that there are 3 trims higher than the RST (Trail Boss, LTZ and High Country), but I really wish GM gave some more interior features for the RST and TB. For those not wanting to have all the chrome on the truck, we have to sacrifice features that were on the monochrome LTZ Z71 in 2018 - seat memory, ventilated seats, electronic rear child locks, particularly. Beyond this, I think for an MSRP of $54K, we should also get a digital dash center like the available tech package offers on the LTZ & HC. Why not just make that an option for another $$$? I would have bought it. No gas/brake pedal adjustment. To be honest, I never really found this feature all that great in GM rentals I've driven. However, the new Silverado pedals seem to be positioned a little too far forward. Combine this with the fact that the telescoping steering wheel does not, IMO, telescope towards the driver enough... and I just haven't felt like I have a comfortable driving position with the 10-way power seat. I'm 5'11", so not short or tall. I've finally adjusted and found a position that works, but my 2007 seemed to have a better, natural position for my arms, elbows, feet, etc. No power passenger seat. For $54K, c'mon, GM. No built-in nav. I use Apple Car Play, but it costs me an extra $600 to have the nav installed on my RST? That's lame. It's 2019, GM. I really only want this for the speed limit indicator in the driver info center (DIC) in the dash, ha. Badge placement. Why did they put the Z71 badge on the upper front fender? Weird. Put it as a sticker on the top rear fender, like it has always been. No color-matched mirror covers. Mine are glossy black... which look okay with my Satin Steel Metallic paint job, but why not just color match them to the body? Lacking LED lights. I don't get why you put LEDs in every other place on the truck lighting besides the turn signals and the back up lights. That's just weird. Dashboard. This befuddles me. It looks cheaper and more basic (besides the DIC) than previous models. I realize most of us just look at the digital MPH on the DIC now, but it just looks cheap. Power down windows. Why only for the driver, and not the others? Bed / Cargo LED lights. Why no switch in the bed to turn these on? Mid-vehicle signal. With a truck this big, I don't get my GM did not put a turn signal indicator somewhere on the middle of the vehicle. I get nervous changing lanes on the 6-wide stretches of interstate going 75mph in DFW. This would have helped a lot. Plastic-y interior. Though I do like the feel of the interior overall, now that my truck has started to collect some dust / dirt in the interior, I'm noticing the cheap-looking plastic mold feel of some of the elements in the interior. I appreciate the wood finishes in places, but that hard plastic feel around the console, on the doors, etc. just does not feel like $54K to me. It does not really feel "cheap", but just not as plush as I would have hoped for. I still think it feels better than the F-150 interiors I've been in, with all the knobs, buttons and different plastic components the Fords tend to have. Fuel capacity. I don't get why GM did not create a bigger fuel tank on this new model. 24 gallons, seriously? My 2007 had 26 gal, and even my wife's minivan has 21! Fail. Interior color options. Two options, seriously? Antenna. Again... $54K truck and we still have a 3 foot whip antenna? It was the first thing I got rid of, less than 10 min after I got home from the dealer. So ugly. Things I like... Design. I know this is polarizing, but I think it looks amazing. In 1-2 years, after Ford refreshes, I guarantee this truck will look like the forerunner in style, and not the oddity. The body lines, the grill, everything looks fantastic, IMO. I like the Silverado much better than the Sierra, too. The grill space on the GMC is just too massive and hollow-looking to me. LED lights. The DRLs, LED tail lights, and the LED headlights are fantastic. Interior updates. GM finally made a rear seat with good legroom, and comfortable seating position. Adding the rear air vents is honestly what sold me on getting a 2019 vs. a 2018. About time. I love the spaciousness of the cab, and though many people feel the center stack and overall interior feels "cheap", I feel otherwise. I think the buttons are all well placed, and I love that GM is still doing manual HVAC knobs. No center console shifter. At first, when I was looking at the F-150s, I thought this was an upgrade vs. a column shifter. Then I sat in one. I like GM's way better. The new one feels fantastic, too. I like that I have the entire lower console available, and that I do not have to reach over the shifter in order to get my coffee. Centering of steering wheel. GM finally got this right. All those years of the steering position being off-set slightly. They finally corrected that. It's much more comfortable to drive now. Steering wheel controls. I'm glad GM went back to hard plastic buttons for these, vs. the soft push-buttons on the K2 models. The covers on those buttons always seemed worn out quickly on my friends' K2 trucks. I like the more durable, actionable feel of the plastic. Infotainment Screen. I know a lot of people wish it were larger. I am not disappointed with the size. The screen is very crisp, and super responsive. Bluetooth engagement is very fast with my phone, and I like the display options on it. Better wheels again. I'm so glad GM went back to real aluminum wheels, and not the chrome-clad stuff on the previous generation trucks. My 20" 2007 aluminum wheels looked great, and I think these new aluminum wheels are the best ones GM has made in a long time. Rear tailgate. I love the electronic button and remote unlock /drop from the key fab. The lightness of the tailgate is also amazing. The bigger step footwells in the bumper are a great improvement, too. Cargo bed. Wow, this thing is legit. I cannot believe how big it is. I'm glad it's steel still, too. The increased tie-down options is a huge plus. Rear seat storage. I LOVE the storage compartments in the seat backs. Fantastic use of space. Powertrain. I never wanted the TT 3.5L Ecoboost. I think it sounds terrible at the exhaust, and I don't want to tow 12,000# with a half ton up an 8% grade. I love the growl of my 5.3L V8, especially when I hammer on the gas. The new 8 Speed transmission took some getting used to (coming from my 4spd+OD 2007), but I've found that if you really drive the thing, it responds terrifically. Very smooth, and the acceleration from 30-50mph is impressive. Like... put you back into your seat fast. It is a lot of fun. MPG. I've been averaging nearly 18mpg with my very in-town driving. This is WAY better than the 13/14 I was getting with my AFM 2007. The only time I've really done HWY driving was when I brought the truck home 200 miles from the dealer. I did 75mph avg (going 80mph the first hour), and got nearly 22mpg. Wow. Capless fuel. Love this. Ride quality. Wow, this truck is unbelievably quiet. It's still a truck, so it doesn't ride like a cloud, but it's very smooth on the HWY. The handling is very crisp, and I always feel like the truck is poised when moving around at high speeds. Never loose or rolling too much on body center. Mirrors. I know some are puzzled by the placement of the mirrors on the door itself, but I find the FOV excellent with these. They are big, but not too big. And I really love the blind spot mirror in the corner of the driver's side mirror. Just not sure why they didn't put one on the passenger mirror, too. Badging. Besides the aforementioned confusion about why GM put the Z71 badge on the front upper fenders, I really like how clean and empty the truck is of obnoxious brand badging. I really love the throwback "CHEVROLET" stamped into the rear tailgate, too. Keyless Start/Stop/Entry. LOVE this. Leaving the fob in my pocket and pushing the really great buttons on the handle to unlock is excellent. GM did a great job with this. So far, the fob has worked flawlessly for me. Option button placement. I really like the row of option buttons below the center stack. It's easy to reach them when resting my arm on the console, and very easy to see. Cleanly designed, too. I also like the new trailer brake placement, as well as the placement of the 4X4 selector/lights, etc. buttons on the left. Dual exhaust tips. I personally think these look really good integrated into the bumper. Because they are, I don't have to worry about a lower rear clearance, backing into something that would rip the exhaust off. Plus, the engine tune coming out of these babies is awesome. It's fun to turn on the rear camera sitting at a stop light on a cold morning and watch the exhaust roll out of the dual tips. Bose sound. I know the sound gurus out there have issues with Bose, but this is a huge improvement over the standard GM stereo system. Bed outlet. Actually, the whole charging package on this truck is fantastic. USB and USB-C in the front console, center stack, and rear seat is excellent. Then having a full plug in the front console and rear bed is really nice. Value. GM owners know our trucks hold their value really well. At just under $44K, I know this truck is going to hold its value for a long time, especially since it's a T1 model. A similarly optioned 2019 F-150 was around $61K. That's just crazy. Even though I have a beef with GM for not putting certain features in the truck at this trim / option level, I think the value is very good compared to Ford. Rear headrests. I love these. Finally comfortable, and easy to move down and out of the way. The center drink holder / arm rest is also very nice. Rocker panel paint. I like how GM did this, with the "roughed-up" paint job so it is more durable to chips, etc. There are probably other things that will come to my mind. If so, I will add them to this. Here's a pic of my truck attached. Hope this review is helpful to any prospective buyers! I'm no truck reviewing pro, nor am I a gearhead. But I've always loved owning trucks, and this new Silverado makes me feel proud when I drive down the road. I get a lot of head turns, and it's fun to own such a capable, enjoyable vehicle!
  12. I was hoping some of you might give me your thoughts and recommendations for which plugs to buy... ? I have a 2002 Silverado 5.3L v-8 Vin code T The manual list Denso PTJ14R15 and NGK PZTR5A15 AND the manual list a .060"gap. When I go to local auto parts websites there is no help for these part numbers and I am unsure of what plug and what plug gap I should use. I currently have a misfiring truck that runs like crap. Looking to replace the plugs, and possibly all of the coils, maybe the spark plug wires. My truck sits for months at a time unused but did run good before all this happened. Initially I thought it was bad ethanol gas from sitting unused but have used a lot of SeaFoam and have run through three tanks of pure gas. When I discovered possible coil failure could be the problem I started reading about issues that could cause the misfiring. Plugs are relatively cheap and I thought maybe I would replace them anyway and if that doesn't fix the problem take it to a shop for evaluation. I am not equipped with any specialty tools or knowledge to know much about what I am doing. I can change plugs if my standard sockets and wrenches will fit in the tight spaces and I can plug in new parts but don't want to buy parts I don't need either. My truck only has 70k miles on it. I have a friend coming over with a code reader to see what it might show but I don't believe it will tell you exactly what part to replace, just what the general symptom is and possibly which cylinders are misfiring. Could be fuel injectors too? Someone who tuned my truck years ago put in Denso TT16 plugs or something like TT but definitely 16 was the number. I do have long tube headers and a cold air intake but no power mods on the engine otherwise. Any and all help or suggestions are welcomed. And thanks in advance for any assistance.
  13. trying to put together a swap for a 75 custom deluxe and was wanting the 6l80 transmission for the efficiency. would it work with a 4th gen 2005 5.3 out of a silverado?
  14. I drive 2000 silverado 1500 5.3 vortec. Well here for last month or 2 notice decrease in power etc. Requires more throttle going up hill,rough idle or inconsistent idle, and also on it occasionally will hesitate or the best description is it will start like cutting back like a train (chuga,chuga) with almost no power it just cruises the speed I'm going mostly in lower rpm from a stop.Ive changed fuel filter,oil, oil filter (just because why not) today i got my cats replaced and exhaust system installed. Problems still occurring, so that only leaves a vacum leak or maybe a bad sensor (mass air flow)?? Idk please help or point me in right direction!! Thanks in advance
  15. So about a week ago, I got the "Left rear indicator failure" I figured it was just a bulb. So I put it off for a couple days. However, this Saturday I decided to change out the bulbs. Well the bulbs are good and also the fuses. I checked the wires that come from the junction box and they where all good. Any idea what it could be? The running lights work, but when it comes to stoping and the turn signal I get nothing. This shit is driving me crazy. This is what I've been told: - I need a new Junction Box. - I need to replace the fuse box in the engine bay Please help, thanks for anything!
  16. I have a 2014 Silverado. For some time now it's been making this noise from under the truck. Friends have guessed at it and so have mechanics and we cant seem to figure it out. The guesses I've heard were lifters, rod knock, transmission teeth, drive shaft, and engine misfiring.. moat of which are not the case as the truck still runs well and shifts properly. This noise is also accompanied by a check engine light (Not Flashing) so no misfire... I'm just confused as hell and just want to fix this thing.... also this only occurs while driving at a steady speed only between 1000 and 1500k RPM any faster or slower and the noise goes away. Here's a reference video so you can hear what I'm talking about.
  17. 2015 Silverado, 5.3 Gas with just under 34,400 miles. I've just started noticing that ??burnt oil?? smell after starting the truck up. Usually after sitting all day at work, or overnight in the garage. Only way I can describe the smell is by the 2003 Silverado I drove at work for years that ended up having a new engine put in it. I don't see any puff of bluish/white cloud on startup. Only noticed it like in the last week. Usually I'm either remote starting it when it's cold out or getting in and starting it up. So I never smell it. It's only 16 miles round trip to and from work with many more stop and go's than miles. It only had just under 11k when I bought it in Aug 2017. So what, 23k in 18-19 months. It runs smooth, idles smooth. Should I worry about it? The way things have been going lately, it would be just my luck to have a screwed up engine.
  18. Hi everyone, I'm new to the form and hope I'm doing this right. I was looking for some input on an issue I've been having with my truck recently. After the truck gets warmed up and drove around for a while it will make this grinding/screeching noise from around the transmission area. It will only make the noise when the vehicle is in drive/reverse and I am stopped on the break. The noise goes away immediately after it gets switched to neutral/park or when the truck gets moving with a very minimal amount of throttle. I do also have a cosra cat back on the truck. The only mod done to the truck. I've had it in and out of the dealer at least 4-5 times and of course the issue can not be replicated while the vehicle is in there possession. The one time that it was making the noise when i brought it in the shop manager immediately was pointing fingers at the exhaust. He was trying to tell me that it had to do with a back pressure issue since its not the stock exhaust. After i got home and looked at gm's site for there cat back and it states that it relieves back pressure up to 66% so now i know he is just making stuff up. i also recorded a video clip of the noise it was making that i will link. If anybody has any clue on what the issue could be it would be greatly appreciated.
  19. Hey guys, so my 2004 Silverado's LM7 is at about 174k Miles and every oil change since about 156k (I bought the truck around 155k) has been full of metal. When I got the truck it made zero noise, but a month or two in, I noticed when it was warm it would make a clattering noise for about 30 seconds on start up and go away, did not do this on cold starts. I then noticed my oil looked like glitter with a few decent sized shavings. being a broke 17 year old, I ignored it. it has progressively gotten worse, during colder weather it knocks on cold starts along with the warm start clattering. Oil pressure currently is about 45 psi cold and 30-35 warm and 45 around 2500rpm warm. When I frist got the truck those readings were a bit higher each. Im curious if this sounds more like a cam and lifter issue or bearing issue. My friend's 2003 LM7 with 112k miles makes the exact same clattering in the same way mine does but his oil pressure readings are slightly better and I don't think he's ever found metal. Im stumped, and its too cold out for me to investigate. The truck has been parked for 2 months from a separate issue and Im wondering what to do with it at this point considering the engine issue.
  20. I had a flashing check engine light on my 2016 Tahoe (5.3 with 21,000 miles) that would come on for 30 seconds and then go away. Happened to me twice, about a week apart, going up a slight grade at about 20% power. Truck drove fine and didn't seem to be really impacted by it. I took it in yesterday to the Chevy dealer to have them check it out. They did not tell me the code that they were able to pull but let me know they were going to replace the lifters in it. Seems like a pretty big repair job.. the service technician said its an expensive repair. Curious to hear if others have also had this problem. Hopefully this is just a one off and will be fine going forward. Luckily I have another 15K miles of warranty left so will monitor closely. This is my first GM vehicle in 8 years after returning to the brand. I've also been battling the vibration going over 70 mph but have it pretty well isolated to the tires. Truck has the factory 22" rims which probably don't help the problem. Lowered PSI in the tires to 33 psi and recently had them balanced/rotated which helped. Will probably throw on a set of Michelin's shortly to dump the factory Bridgestones.
  21. I’m looking for any information on swapping gen3 5.3 With a gen4 controller (I want to use the 6L80e transmission.) I know the knock sensors are in the valley cover and it has the 24x reluctor and 1x cam sensor. I’ve heard it is possible to relocate the knock sensors to where they are on gen 4 block and swap reluctors and cams to work with the gen 4 controller, does anyone have any experience with actually doing so?
  22. I am sure this has been brought up in other Topics but I cannot seem to find an answer so here it goes... I have a 2007 GMC Sierra SLT CCSB 4x4 5.3L M engine, on Saturday afternoon I disconnected the ground on my battery to add an aftermarket sub and amp tapped off of the Factory Bose amp. After wiring everything up correctly (just running wires) not even installing the amp or subs I decided to reconnect my Battery and fire up the truck... Funny thing is after plugging it back up and going to start it, it immediately said Service Air Bag, and would not start.. I have checked fuses under the hood, under the dash and on the instrument cluster fuse box and all my fuses are good and working! All doors, windows, lights, remote lock, unlock and alarm work but the truck won't start I have tried the 30min key relearn and redisconnecting the battery for 30 min. Normally my truck has a TPMS Service light on due to me having a bad sensor but it isn't even on right now! Everything works but it just won't even crank it just dies in a sense (it acts like it loses power but as soon as I release the key from start position everything comes back (lights up as normal) seems like I am locked out of the system. Scanned with a Snap On code reader with personality keys... I get a B1370, B1011, U0140, P0690 and a airbag code that I don't recall (I'm at work) after clearing the codes only the B1370 and the Airbag code return.The Service Engine soon light isn't even on either I only get these codes with the snap on scanner.. they don't even show up on my basic scanner.. Yes the battery is good also tried jump starting it just in case checked all fuses and relays, starter works with forced relay and key on but will not start also replaced my ignition switch. Another off topic question is what does The TP in the under the hood fuse box diagram mean? it has it near the 41 Fuse it says TP twice then at the bottom it says TP and has like a book with a key next to it... I'm at a loss right now with what the issue is any help is Appreciated!
  23. I have 2000 silverado 1500 with around 218k miles on it.

Realized ac was blowing warm so i turned ac off waited 5 or 10 mins turned back on and was cold as usual.Long story short still having this problem, wondering what it could be causing this. Btw new to the forum any info would be appreciated. Thanks
  24. Yesterday I had to run to Phoenix and back for work supplies. My company truck is a 2016 GMC Sierra 1500 long-wheel-base 2wd with 5.3L V8 (former Uhaul truck). I used cruise control, I meticulously went the speed limit, and I used the air conditioning and stereo during the trip. More than half of the trip I was hauling over 1500 lbs in the bed. By the time I returned the dash was telling me about 25 mpg for the round trip. Manual calculations at the pump said 23.49 mpg. In my opinion that's very good. Here's the video:
