  1. Adding a drain plug is one of the first things I do on every transmission I have to service. I take a regular nut and castle it with a cut-off wheel. The slots allow fluid to drain; without them, any lip formed by the drain plug retainer will hold fluid, and more importantly, settled particulate (which never comes out with an extraction pump). Then I drilled a hole in the pan at a location that wouldn't interfere with either the magnet or the filter. Then I MIG welded the castle nut, slot-side down, above the hole. I used a new drain plug to center the nut and clamp it down for a brief tack. Drain bolts, with sealing washers, are readily available from any FLAPS, either 14 or 15mm hex head (I forget which). This is also the upgrade I highly recommend for anyone with a BMW; toss the 8mm allen drain bolt as far as you can throw it and replace with a GM drain bolt. Now, ATF changes are far simpler and easier than even dicking around with a fluid pump; remove drain bolt, let fluid drain while you walk away. Slightly pull dipstick to allow air. Come back, wipe pan, install bolt, fill trans, done. Easier and quicker than engine oil. The principal that I use for every machine I own is that maintenance prolongs their lives, and maintenance will occur more often when it is easy and convenient. Therefore, ease of maintenance prolongs a machine's life.

  2. Swapped out Fox 2.0s with 80k on them, for new Fox 2.5 with resi. Direct comparison is not fair because the old ones were worn out, but I say I really like the ride and control of the new ones. From order to delivery was only 7 months, so they'd better be good. While I was at it, I addressed low psi in the brake vacuum, by replacing the vacuum pump. My truck is an 2018, but had older part number (12669488). So I got new one from Amazon (100$) part # 12696313. Checked Brake Booster Vacuum before at idle: ~12psi, and dropped to 1-2psi on peddle pump. Checked after: 14psi at idle, and 3psi on peddle pump. Not much difference, but the pulley bearings were going bad, and I replaced the belt, so still worth it at 80k.

  6. Or, just reaching an arm up with a garden hose to spray out the inside of the body panels. Every time I wash a vehicle, I start with the underside, nooks and crannies of the body seams, frame channels, etc. I'll even fill the boxed frames with water to rinse out salt and sand. One thing I learned as a teenager was to use a hose nozzle pointed back toward my face to clear the GM fender lips of debris, shooting water from the frame-outward. Just spraying out the inner fenders never removes the dirt/sand that traps moisture and sits above the fender lips. Forget about my '16 not having rust, but my '84 and '86 GMs that have lived outside their entire lives through upstate NY winters are also rust-free as well. It's a lot harder to repair rust than it is to prevent it.

  7. There’s one person on here who’s very entertaining. Seems very knowledgeable. Has had every job and degree. And can’t be swayed. Some I’ve learned from, got me to think. I’ve even been on his sh$t list. I like to challenge. But I’ve actually seen the results. That would be Grumpy. I’m sure I’ll piss him off again and often. I like to challenge.

  9. I installed one on our 6L80. I had a friend weld it in place. Works great. Got the plug from Summit Racing. I did order a new pan to have it welded into so that when I dropped my old pan, I had it ready to go up.

  10. @Jettech1 I quote @customboss to toss light on the coils not the writer. "Coil on" and "coil near" systems need a trigger and that trigger is a transistor. For some reason they decided to place that transistor in the coil (in most vehicles). Transistors are wonderful things but are heat funny as they age and unlike a hard switch. Heat is a killer and an unpredictable interrupter of current. It works, it doesn't, has a good day then it doesn't. Works on the bench and not in the car. Works with it's cold but not hot or hot but not cold. Good at light loads but not heavy. You get the picture. Customboss uses the word "Partial" but it's more "intermittent". Can be hard to hunt down without a laptop and on the road. May even require a 'rolling road' to find. It can happen to new units. Not every pig born is perfect. Fuel GC tests says 'there is a problem' but doesn't tell you exactly where that problem is. Static coil test may say all the world is roses (while you're looking at it) but the GC can't be lied to. Allot of people, experts in the field, will tell you under 2.5% for a GDI is 'normal.' They also say a quart in a thousand miles oil consumption is normal. My take on it is that under 0.5% is absolutely possible. Over 2.5% it isn't likely the ignition system. And I know for a fact that up to 8% will not trip an MIL/CEL but it will crash a set of rings if it goes on long enough.

  11. Well, if I tell you I pulled a 58 in the lottery you may figure out my age... the second year of the lottery. Between slip disc, kidney stones and afib I am afraid if I start a project like this I may not get it finished, so I leave it up to the young in's, LOL I hope to make the transmission last as long as I need the truck which is less than most of this forum.

  12. I haven't bought it yet, but this is what I planned on using. I'm also a fan of single height hitches. But I like to be able to adjust height based on load. If the back of my truck has 2,000# in it vs being empty it's going to change the ride height of the rear end. I also have 2 different trailers right now and may pick up a 3rd. So there's that.

  13. What a joy to not have to worry about scrapping the undercarriage when driving over the humps. Back in 2016 we bought a SRT Charger. That was a beast too, but you always had to worry about scrapping the front bumper and undercarriage of the car. This time at the Starlight Drive-in in Atlanta was a joy. The only thing that was kind of annoying is the radio would shut off after 20 minutes or so. All it took was a press on the on/off button to bring it back it to life. But we both were able to stretch out, lay back a bit and not worry about a thing. The thing that made us laugh is that because we were nose high, the cars that drove by, we couldn't see them. LOL...anyhow, a great drive-in vehicle bar none. No one was going to overshadow our view and for the others there, they parked onside of us. So it was all cool....my wife is so not a truck person, but she loves our beast. What's not to love? Oh, and the 2 movies kind of sucked. The first one was knock at the cabin...super weird....the second one was Megan.....ummm well....yeah. So for us it was about the experience, not necessarily the movies thank goodness....We've gone there probably 100 times in the past. Great experience for all. If you live in the Atlanta area, no....it's not a great part of Atlanta, but we've never felt unsafe or threatened in anyway, although I will say we are both armed just in case. Go there with the family, you will have a blast!!

  16. For those of you who have installed a drain plug in your Transmission pan I have questions… Is there a certain spot to avoid? Do I need to have this welded in place? I only have a wire welder so I will have to find someone who can weld it for me. I purchased a Derale-13010 TRANS Pan Drain Plug and have a new pan so it is ready to go in at the time I drop the original pan.

  17. @Mark Duke Hot idle in neutral or park is 4-8* Hot idle in gear is 8-14* Cold adds about 4 to each A/C adds about 4 to each. It will go negative on decel near the bottom of each gear as much as a dozen. That's TIR. Hope that was helpful.

  18. Upgraded the OEM fog lights to a set of Baja Designs Sport Fog Pocket Light Kit. Install was super easy. Assemble the mounts, undo three screws holding the old one in, mount the new fog light with the same three screws, and plug into the existing harness (no wiring needed). The light output on these are crazy bright compared to stock ones. I went with Amber but they have white as well. Check them out if you are looking for an easy upgrade. https://www.bajadesigns.com/products/chevy-gmc-squadron-sport-fog-pocket-light-kit-chevy-gmc-2019-2021-silverado-sierra-1500-2020-2021-2500hd-3500hd/?page=1&vid=152887&sku=447518

  19. I'm very Happy with my Diode Dynamics, I have the brighter version and with the driving light lenses they were just too much for public roads, I talked to Diode Dynamics about the issue and I ended up buying fog light lenses (They are changeable, including the amber lenses if you want to change) and once I put the fog light lenses they were perfect, no flashes from other drivers and great lighting.

  21. Chris, when they replaced the radiator did the new unit have a 3- or 4-inch squared piece of aluminum tape over the upper left hand (drivers' side) area of the fins? You can see it through the grill. GM's first pass at this issue centered on the thermostat sensitivity to cycling. Fix was a thermostat. The second was this tape fix. Thermo-shock was considered the primary issue. Mines had that 'sweet smell' for years and I add a cup of fluid about every other summer. Could never find a wet spot anywhere. They rot, like they all do, from the inside out. Starts in the seam. Wool Wax, Fluid Film. Blaster Surface Shield. Some sort of lanolin sprayed between the panels that can seep into that welded area is a huge help. As is spraying the wheel wells on the tire side. That seam can be accessed from the box by pulling that plug above the inner wheel tub. Or a wand after pulling the tail lamp.

  22. Today I begin the last year of my 60's. It is funny when I think of memorable birthdays, they usually centre around childhood. I not a fan of too much attention and most of my adult birthdays are indiscernible. Receiving a few phone calls and lunch out with my wife suits me! I truly appreciate having so many birthdays as the option is totally unacceptable!!

  23. Shadow gray, definitely way more room than the factory storage. The factory one is pretty useless. For comparison, here is the Du-Ha brand one I installed in my truck. Can sort of see one of the dividers in place on passenger side in 2nd pic. Don't mind the dirty interior; kids do that, plus it's been too cold to clean it.

  24. I've bought so many CAI's over the years for my past owned vehicles that it isn't even funny....well funny of course that I did it...lol....anyhow, I never noticed any kind of difference when I installed them. BUT, after running them for several months, and getting the idea that hey, I'm going to install the factory intake back on. That's when I noticed the difference big time. I've bought Airaid, K&N, you name it, I've bought and tried most of them along with drop in filters. But this one company that caught my eye several months ago is S&B. For 349 their CAI is very well built and to me quite impressive. You can buy it with an oiled or non oiled filter. I think I'm going to buy one. What ta hell. I like intake growl more then exhaust growl. For you old guys and gals out there like me, it will probably never sound like the old chevy 350 with the 4 barrel carb with the top of the air filter breather flipped over to expose the whole filter......that sound was amazing........yup, the quadrahog sucking in air big time......LOL...be well all and what do you think about it? Here's the link to it.... https://www.sbfilters.com/cold-air-intakes/silverado-sierra-2500-3500-6-6-intake-75-5158?variant_id=780

  28. I recently changed out my coolant thermostat on my 2016 5.4L 6 speed after experiencing problems that suggested my stock thermostat was sticking open. I verified with an OBDII reader that I was having undercooling problems. I saw a recommendation by @16LT4 that he used the Motorad 194⁰ instead of the stock 207⁰ thermostat. I did a bunch of searching and saw that I wouldn't have to change any tuning like I might have if I went to a much lower temp thermostat. I also liked the idea that coolant would start fully circulating at a slightly lower temperature. I figured I would give it a try. The install couldn't have been any easier. Swapped it out in no time and the dash temp gauge went up to 210⁰ mark and stayed solid. I didn't verify with the OBDII the actual temperature but I know that although not completely accurate, it would show larger changes and it wasn't moving so it worked. When I was searching, I kept looking for more information about thermostats and cooling especially when towing as that is important to me. I wasn't finding much. I am assuming that getting the coolant fully flowing slightly earlier could only be a benefit. Most of the time when towing my 25' toy hauler (6200lbs loaded) I had no cooling issues and travel mostly flat or slightly hilly areas. But when climbing some extreme grades last year, I did see the coolant temp, oil temp, and trans temp rising significantly. I'm aware that trying to race up grades is a bad idea and also use tow/haul mode as well as proper gearing. I did change the trans thermostat to the updated 170⁰ one after this. (Ooops, I meant the updated 158⁰ one...) Now I have the 194⁰ coolant thermostat installed. I'm hoping that the updated trans thermostat change out as well as the newly installed coolant thermostat can only help with providing more efficient overall operating cooling when towing? And by changing from a 207⁰ to a 194⁰ coolant thermostat, is there any other benefits that I may see?

  31. A B C D E F G H I J K L M N O P Q R S T U V W X Y Z All the letters of the English alphabet. Anyone that can read English knows this. For those that cannot read, it means nothing. Just random shapes. The educated persons ego may incline them to look down on the ignorant. The ignorant ego may find embarrassment in the inability to read. Those are the elements that cause conflict. Ego. To a person that cannot read these words on this page have no effect on them. And will have no effect, publicly, unless someone that can read calls out their ignorance. What they will be inclined to do is defend themselves. It may take the form of something like; " No one in my family for six generations could read and we got along just fine without it". And it will indeed be true. "Just Fine". The educated one's ego will take exception to that position and sight all manner of benefit that extends beyond "Just Fine", and that too will be true. Whose error it greater? They are both driven by ego. I haven't an issue with either position. What I do have an issue with is a stupid defense that goes something like, "There is no such thing as an alphabet". "Words cannot be written." Even a person that cannot read is not ignorant of the things they watch others do. Read. The ignorance then is 'willful' and defense unreasonable, irrational. Intentionally hurtful. But so is insisting a person learn to read against their will. It's called "Free Will" not My Will. I said early in this thread having a can 'hurts nothing'. I also said the liquid it the can may not be all oil and it MAY be useful to have it tested. And then I let it go. @Jettech1 did not seem interested in finding out. Who am I to argue with him. No greater good is served. Besides, his thread, his house, his rules. I'm a guest.

  33. Most threads get derailed here because of a difference in opinions or I'm smarter. I occasionally play poker with an retired engineer and a retired professor, they both think they know it all. I proved to a mechanical engineer he was wrong by showing him he was wrong. He wasn't happy. An education or as I like to say, a paper holder doesn't mean you walk on water. While I respect the knowledge the problem is the EGO that comes with it. I also understand testing things is the best way to know what is happening. I'm a big proponent of keep it simple. As I have said before for over 50 years I have never had a drivetrain failure by simply changing fluids and doing preventative maintenance. My system has worked, so it if ain't broke.............

  35. No real need at all to raise the shift pressures or anything like that. The basics would be to quicken the shift times some, they are kinda soft in my opinion from the factory. Quicker/cleaner shifts should help with clutch life. Turn off the torque converter for gears 1-4 and only allow it in 5th and 6th. Then raise the lockup mph settings so it can't lock the converter while lugging the engine at 30-35mph with 1,200rpm. I extend the 5th gear lock up to around 45mph and 6th gear at nearly 50mph. It drives way better this way. Do this would also require that you change the shift mph speed settings to match your lock up settings. Don't allow 5th gear until 44-45mph and same for 6th. Gaining fuel mileage, good luck. So much of it is down to driving habits and weather conditions. I wouldn't say you can't gain power from a tune but more so you are unlocking what is already there sooner. Lots of changes can be made to make it react quicker to throttle transitions.

  37. I have about 10,700 miles on mine. It has not burned any oil thus far. I think something must be wrong with mine. From what I am reading in this thread and according to GM, it is normal for the 6.6 to burn oil. Something is abnormal with mine. I should make an appointment ASAP to see why mine is not consuming oil.

  38. Declaration of Independance paragraph 2: We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness. Even the framers knew that freedom, whatever you think that means, knew it is granted not from men but from God. It cannot be taken, and it cannot be defended by one people without equal or greater suffering for another people. Europeans come here to rid themselves of religious tyranny and slavery and imposed it on the people they took it from by force and those they brought here against their will. (Taking their freedom). There hasn't been a free expansion into an unpopulated area of earth since I couldn't tell you when, and even when lands were empty for the taking people of all government styles and religious beliefs still took from others first. Imposing their will and stripping the native populations of rights, privileges and life itself. You can call me whatever you like but you cannot call me a liar. History proves this out. You can spill as much blood as you like in defense of an idea whose very substance is standing in that same blood of those that preceded them; but ALL MEN are created equal. Not just those whose ideals and customs you like. You cannot obtain PEACE by WAR. The best man has done so far is force submission and call it peace. The Cold War itself was intimidation by threat of VIOLENCE. Dad dug a bomb shelter in our backyard during that time. Was he FREE of the fear of violence? We didn't do fire drills in my school. We did Nuclear Bomb drills. You can't even go to Target anymore without the threat of some 'free' man shooting you. Some sixth grader shooting your teacher wife, sister, daughter. Some boys in blue gang beating your sons and daughters to death. Some idiots on the road exercising his RIGHTS to ignore the law if no one is looking canceling your right to life in peace or live at all. Most people can even define FREEDOM. Human rule, period, is the issue.

  39. I know that. I’m implying that it is not uncommon for a tech to inadvertently pump the amount of oil based off of a different spec i.e. the 6.0. I had that exact thing happen to me before and have heard it happen to others as well. edit. Just looked. A 6L takes 6qts. Easily possible only 6qts went in at the dealer. most of these techs don’t give a damn about engine size and which engine is in which truck so it’s very likely it happens a lot.

  41. Hmmmm, the ship of state in US and other democracies like Canada are simply a vehicle of life for many to enjoy fruits of life there but do nothing and contribute nothing to its condition and health. Covid affected s death and injury is a DIRECT result of how that boat floats. I've never been a casual observer my former christian faith and duty to constitution drove that and duty drives it today. The USA is no titanic. Stan in particular feels same way we just disagree how to get there. I just won't ever support overthrow of the constitution and when Iran took our hostages I did something to get them back although it cost USA blood and treasure. Many of the readers here like Grumpy seem to not get that the more you have invested in this constitutional democratic REPUBLIC the more you grieve when you see 70 yo men whine about its health but never gave a thing but minimal taxes and voting ( maybe). Every one of you who are not veterans ought to go to your nearest VA hospital and come back and report how the action men and women are doing who allowed you the right and privilege of complaining, enjoying roads, jobs, raising your family, and worshiping any way you choose in FREEDOM.

  42. I have a 2019 6.2 max tow 4x4 with 10 speed. Have a 5609lb dry travel trailer. This truck pulls it without reservation. At almost 13000lb tow rating it also leaves more than enough margin. I did add airbags and a WD hitch to smooth out any bounce. The WD hitch would also be needed on a 2500 for control, but likely not the bags. Overall I'm very happy with it over a 6.6L 2500.
