@SSGUNNER OH also here is another thread discussing this same issue. What is quite humorous to me is the very last post. Guy says while at the dealership be diagnosed for this transmission error, he gets an onstar e-mail saying his battery was low. He calls the dealership to tell them to replace...
@SSGUNNER Thank you for reviving this thread from the dead, people need to know because at this point in 2026, unless your purchased a 2021 certified pre-owned, warranty is looong over! It could be a completely different scenario now, but at the time, the stealership did not know a fix and were...
@KMeloney I will have to brush up on my photography skills (Just a quick 1st pic seeing it for the first time getting it from the dealership yesterday…. My focus was getting behind the wheel)
@Sgt1411 First off, beautiful hoe you got there

Hello all- Just upgraded my 22 to a 26 and trying to figure some things out…..
Please may I pick your brains and get your feedback if you have done any of the mods and I think this goes without saying but post pics of your rig when you reply….
Question #1: This is regarding the side marker...
@Big Mama Hey thank you for the reply. No I sure didn’t. I kind of forgot about the thread though because my deal on the Tahoe I was scooping up fell through, the guy sold it to his Cousin who needed a car. Darn it! But hey I praise him for family loyalty.
Anyways, I am back searching, and...
@WalleyeMikeIII You are exactly right that it gets much colder up north, and y’all’s Tahoes aren’t freaking out.
