Hello all. I own an 18 Silverado 1500 LT , double cab, 6’6” box, 6 spd transmission, I have opted to put 26” status alloy empire wheels with tire size of 305/26/30. Stock transmission gave out. Stock Transmission went out. They said torque converter and pump went out then everything else went with it. Was able to replace the entire unit with a remanufactured from GM. 1 month later, back to the shop (dealer). They covered the repairs because it was under warranty but if it goes out again they won’t because they believe it is the rims causing the trouble. However they will cover if it goes out with stock wheels. Which I will be putting back on. Has anyone else experienced issues with this type of truck and 26” wheels? I did research the “Unsprung weight” makes some sense, however only the transmission gave out, not my drive shaft, drive shaft knuckles, diff, just the goofy transmission which I know the 8 speed has had their share of ongoing things. How is it that a truck that is capable of towing 9k lbs has issues with no load on 26” rims. Pulling a payload in the bed of the truck and pulling a trailer should still have the same effect. If I can’t tow anything with the truck, then what is the point of a truck. I have went back to stock rims to see what would happen. Anyone with info ,thought , something sketched on a cocktail napkin would be greatly appreciated. I do thank you all for your time on this. I have attached the service ticket to this post.
Finally installed my UPR can and Airaid intake last week and wanted to give some feedback to anyone interested in something similar. Back story is that we bought a 2018 Yukon XL Denali in Dec then had all lifters n cam replaced 2 weeks after due to dreaded tick on engine with 33k miles. As tech said internals are clean, I decided to go with a can to protect investment especially aftering asking tech and service manager about them and its impact on the warranty. They stated as long as warranty claim isn't affected by catch can, there wouldn't be any issue.
Anyways here's some pics of the installation (plenty of videos are available to walk you through it)
The UPR kit is well designed for a clean and OEM look.
Has anyone ever tried changing the aluminum line to rubber hose crimps for the transmission and oil cooler lines out for AN fittings on and 07-13 Sierra 5.3L? I have a 2013 Sierra and the cold here in Canada isn’t kind to these crimps as I believe the rubber and aluminum have different shrink rates because of difference in material causing them to leak. Replacing them will not solve the problem as the will just do the same thing every year. So what I want to know is if anyone has successfully done this and what fittings did you use?
Hey guys, new to the forum. I have a 2016 Silverado 1500 with the dreaded whine that seems to be the torque converter. I am almost certain that is what it is. The only video I’ve found that has the same exact sound is here
How hard is it to pull the transmission just to swap out a nee TC? Does that sound like the TC or the pump? Anything I need to be sure I do? Truck is still driving fine, but not sure for how long. Any tips would be appreciated. Also looking for the best TC that will last.
