  1. Anyone else experiencing a hard shift or hesitation of the engine when you first hit the gas. For example, I start the truck, reverse out of the driveway, put the car in drive and when I hit the gas, the truck goes toward and then i feel the truck completely stop for a second (hesitation) and then it continues forward, I only expierence this when I’m going from reverse to forward. I come to a complete stop and do not shift to drive when moving backwards still. 🧐
  2. Hey guys so I have a 2019 Silverado 1500LD with a 3.42 rear end with 11k on the clock. I've been noticing that my engine or coolant temp goes passed 210F but when it hits the next 1/8 gauge stick it goes back down passed the middle mark to 190°F. Is that normal for 7000 pounds uphill towing in 95°F weather. Talking about the 5N grapevine in Cali for those who know the climb.
  3. Hi I have a 2007 Yukon that only starts ticking when I am parked at idle for 5 to 10 min,,,starts then gets loud.

  5. I just bought a 2010 Silverado LTZ 4x4 last Thursday and a few days ago it started leaking oil, and now I noticed it smokes from the engine bay on startup. It's not a lot of smoke, but it smokes on startup and smells like something is burning and then a few seconds later it'll stop. I opened up my engine bay and it looks like it is coming from the passenger side exhaust manifold, maybe a worn exhaust gasket? I'm not sure. It is white smoke, and there is a little bit of white smoke coming from the exhaust as well. It's hardly noticeable from the exhaust, but when looking in the engine bay you can clearly see it. If anyone has any ideas what this could be please help me out.
  6. My Suburban was suddenly overheating whilst driving it. Does anybody know if the '07 Chevy Suburban LT have an electric fan? However, I do know that my '07 Silverado (VortecMax edition) has an electric fan.
  7. Hello new to the forum, so giving it a try. First off I have a 03 Chevy Silverado 2500hd 4x4 with the 6.0L in it. Has 180000 miles on it. Been having a faint whinning noise under the front of it in the morning right at the torque converter, goes away when warms up, but also been having a hard shift when going into Passover gear, when in a hard pull or pulling trailer up hill.But only does it going into passover. On saying all this got to looking at trucks history on car fax found that Mr Transmission had replaced the torque converter. So called a buddy of mine who works at another transmission shop and told him everything and he said sounds like they used wrong torque converter for my truck. Said need check it, but have never got around to it, due to health issues. Just been not pulling with it and not running it hard.Well went on for a year now and when got in my truck last week drove 30 miles that day came home parked it. Went back out that night go to town and started it made a loud clank sound (like a gear or chain breaking) from under truck right in same spot where been hearing whinning noise. Sounded like metal on metal grinding after that. I turned it straight off was ran for no more then 2 mins. When try start it again the lights just dimmed. So thought starter, to cold, it raining fix it tomorrow.Well next morning same thing. Took starter off tested good. Came back home hooked chain to truck pulled up hill. Started looking over everything, put bar on crank and nothing wouldn't move motor locked up. Never had problem with truck oil pressure or nothing, have always serviced it, just that whinning. Question is does it sound like locked up motor or can the torque converter be locked up keeping it from turning? Any help or advise would be great.
  8. It’s winter here so I went out yesterday to start my truck and the battery was dead. I put it on a trickle charger for about 7 hours, boosted it up “charger said 90%” when I took it off. I went to start my truck and it fired up immediately, my wipers turned on (to brush some snow off) and radio was playing. I turned it off then went to turn it back on it again fired right up easily then within seconds it slowly shut off. It sounded like something (a pump maybe) was still running while I had my key in (not sure exactly what it was). Read some things about changing a spark plug ? I will try this any other ideas of how to fix this ? Please help
  9. My 5.3 2014 - Silverado makes a clattering noise while running/idling in park. Dealer affirmed "hearing it" saying may be "injector" noise. Advised to put some more miles on it and then bring it back in. They would compare it to another 2014 running/idling at that time. I know my 2010 was much quieter running/idling in park. Friend of mine (Ford guy) pointed the noise out to me when I stopped bye to "show off" my new ride. Embarrassed!!!!!
  10. Hey guys, I want to work on my truck and upgrade it but i dont know what i should do. What are some things you have done to your engine and drive train to enhance performance and add durability? *I drive a 2014 LTZ 5.3
  11. Retro engine

    Just finished up with this and would appreciate any feedback...took about 3 days, alot of sanding and modifying. I ordered vision 55 and BF Goodrich tire, should be here by the 20th. Also a 3" level for the front. Hopefully purchasing a CAI this week. Thanks! Rob
  12. I just bought a 2014 silverado crew cab last week. I noticed a minor shake in the engine while idling (not 100% of the time). Ive felt this in older trucks that Ive owned but figured a brand new truck wouldnt do this. My question is, is this normal to feel this? if so, at what point does normal idle shakes turn into some i should be concerned about? I was under the impression that i shouldnt feel any shakes (minor or not). I have set up a appointment with my dealership, but i want to be prepared when i go in. Also, Im hearing a noise like a belt noise coming from the engine especially when i and parked in a drive through next to a wall. Should i be hearing any ticks form belts? Am i being too picky? Any help would be great Jason
  13. Truck started to make a squeaking noise this weekend, took it to the dealership on Monday. Dealership called Tuesday and said that they could not find anything wrong with the truck and that this sound is normal. Take a look at this video so that you can hear and understand what I am talking about. https://youtu.be/aERzjGAX-aU Does this sound normal to you guys? I also put water on the belt and the noise was persistent so it does not appear to be the belt. Any help would be greatly appreciated!
  14. My 2016 Sierra 2500HD has 176,000 miles on it already and recently started eating parts. The latest part to fail was the reductant tank heater (DEF Heater). Upon cold start the check engine light came on with code P21DD. After a little reading I learned that this can result in “Limp Mode”. I was in the middle of nowhere in Northern Wyoming. Not cool! I drove down to Denver and replaced it that week. I shot this video of the repair.....
  15. 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?
  16. I developed this in my 2003 Silverado at about 36k and ended up trading it off. Anyone still running their GM 5.3L with a pronounced engine slap with higher mileage? Any long term negative effects?
  17. Two easy ways to turn off the engine auto start system in the Chevrolet Silverado 1500 since they do not give you an off switch here's the video link let me know if you have any questions
  18. Hey everyone, I have a 2014 Sierra with the 5.3L, I really don't like posting on the forums for issues because it can give a bad representation of what is generally a good vehicle. My truck never really exhibited any of the usual issues like the vibration but it has had a couple small fixes here and there. Moving seat, rusting frame, etc. this time I just wanted to give everyone the heads up. Well a couple months ago I was driving and the oil pump failed. It took 2 weeks to fix. When it happened I was pretty concerned about any possible damage it caused but the dealer said it looked ok. Fast forward to last week. Merging onto the highway, heard a pop and lights came on everywhere. Got it to the dealer, lifters collapsed on a cylinder. I was without my truck all last week as they fixed that issue. This sunday, less than 60 miles after I picked it up, I went to accelerate in town and heard the same pop but this time it wouldn't even move if I gave it throttle. Towed it down to the dealer and they finally looked at it yesterday. This time they are ordering me a brand new engine. Thankfully I still have powertrain warranty but this is a major disappointment and honestly I don't even trust the truck anymore. What would your recommendations be? Sell it, trade it, keep it and run it into the ground?
  19. Hey Guys, I have a 2010 Chevrolet Tahoe PPV with a 5.3L LMG and a 6L80 Trans (MYC) looking to drop in a 6.2L L9H. As far as I understand it is a direct swap. Would I run in to any issues or codes as far as the L9H not having AFM/DOD? I plan on using the 5.3L PCM and having it re flashed to work with the 6.2 Or do I look for a L94 that has FlexFuel, VVT, AFM like the LMG does?
  20. My 1999 Chevy Silverado 1500 4x4 lost all oil pressure, and then a little later engine shut off. Did not make any loud noises, It just died. When we went to restart it, we could here the starter engage, but the engine wouldn't turn over. So we had it towed, and the guy at the tow shop put a wrench on it and tried to turn it, but was unable to. We have done no further troubleshooting, this happened on January 1, 2018. We assumed it is seized. What I am wondering is what you guys think, is it likely that it seized or is something else more likely to be the problem? If it is seized what part would have seized up? And would it be better to rebuild the engine, or to put a new engine in it? The truck has about 200k miles on it, and ran perfectly before this happened. It is the new body style, btw.
  21. Hello! I am a new member from Michigan. I am pretty sure I have another account on this forum, but it's been a few years since I last logged in, and my email has changed, so I can't get into it. My former screen name was Pinky. I came to this forum several years ago prior to having the drive train swapped from my '93 Suburban 2500 to my '94. I got a lot of great advice & information here, and everything worked out well with that project. I have returned because I have a specific repair challenge, and I'm hoping that I can get some answers once again. My current challenge involves a (piece of junk) 2011 Chevy Equinox 2.4 liter (Ecotec). The engine is shot due to the excessive oil consumption issues that is very common with this vehicle. We would like to avoid encountering the same problem, once we replace the engine, so we'd like to find out what would be involved with retrofitting an engine from a newer model year that doesn't have this same issue. I spoke with a parts supplier who recommended trying to find out if it's possible to retrofit even a 2015 or 2016 into this vehicle. I know this involves changing additional parts that would not be required if we just did a direct swap, but we want to get away from the years that this engine had this problem. I just do not want to end up with an eternally on CEL because of incompatible emissions, etc... Lol. So, we need to make sure we do this correctly. My Equinox does NOT have the AUA option, was manufactured on 3/18/11, and has K as the 8th digit of the VIN. Please give me any info and suggestions you can provide. It's much appreciated! (We still owe on this vehicle, which is why we're putting time, $, and effort into repairing it. So, while setting it on fire or pushing it off a cliff have definitely crossed our minds, neither seems to be a viable option. LOL.)
  22. I have a 2012 silverado and my check engine light keeps coming off and on. The codes read are c0900- device 1 voltage high(history) c0899- device 1 voltage low(history) p0300- multiple misfire detected (History Mil) p0301- cylinder 1 misfire detected (confirmed) there is a slight rough idle on the truck, and I think that my gas mileage has decreased slightly Does anyone have any idea what my problem could be before I take it to a shop, or start replacing parts
  23. Hey guys! Hoping I can get some help on this...my truck out of nowhere started making this horrifying noise on startup, primarily during cold starts. I’m very concerned.
  24. New to forum so sorry if this topic has been discussed in detail already. Just bought a 2015 GMC Sierra 1500 with the 6.2L. I wanted to get your advice and feedback around if a cold air intake is helpful to the engine for HP / TQ./ MPG and just better engine longevity? Any one add a CAI to a 2014-15 1500 with 6.2 if so what kind of gains / losses did you find? Pictures? Recommendations for which brand / model to go with for the Gm 6.2? Thank you,
  25. Hi all, I have had my 2015 Silverado 5.3L Crew for less than a year, purchased February 2015. Currently, the truck has around 14800 miles on it, most of which are highway miles as I make frequent trips between Atlanta and Florida. Today on my way to work in Atlanta my truck just gave out on me power wise, no acceleration passed 40 mph. The check engine light came on and started flashing repeatedly which the Chevy site indicates that to mean there is a serious problem that needs immediate attention. Well I was a very short distance from the dealer near work so I just maintained my speed and tried not to let the truck shift gears. Once I got off the highway I had to come to a stop and experienced really rough idle and some hard knocking sounds. The truck did not however seem like it wanted to die out or stall on me. When the light turned green I pressed the gas and had very weak acceleration, the truck was hardly picking up speed and I couldn't tell what the trans was doing. Anyway, I got it around the corner to the dealer and dropped it off. I am hoping its just a computer module or something that gave out and started affecting things but it honestly seems more to me like a serious mechanical issue. Does anyone have any similar experiences or have any speculation into the issue? The transmission in this truck has always been the thing I liked least about it, sluggish shifts, not knowing what gear it wants to be in, hard shifts and knocking/dropping sounds. Any info or experiences would be appreciated. Thanks, Jeremy
