The TCU in my 2022 Silverado died. Naturally, just out of warranty but only 31000 miles. No GPS, no internet, no Onstar, no over-the-air updates. Local Wifi connects. Tried the reset deal leaving the door open for 5 minutes.
Just curious if anyone else has had this come up on a current generation (T1xx) Silverado? Trying to figure out how widespread this is. Local dealer wasn't exactly helpful.
😠
Cheers.
I imagine the cold winters up here with repeated short runs in town every day for those that live and work in town and given what I have come to learn on this forum with DI engines having fuel dilution issues, and if they don't change the oil until it says to but keep driving it for a while, I bet all that is just lovely on those finicky lifters.
I just did some reading and Stabilitrak is more than a what I had originally thought. It is more of a vehicle control system to help the driver in precarious situations. I thought it was only the AWD system. Now I know.
So I changed the title for this thread to AWD conversion to Z71
Sounds like converting will be a bigger endeavor than I was thinking. This truck doesn't have 2Hi like the Suburban did.
The Tahoe has 4Hi and 4Lo and a button to turn of traction control.
From what I understand the Stabilitrak uses open diff in the front and rear. When wheel speed is not the same the stabilitrak uses the ABS system to slowdown the spinning wheel(s) to transfer power to the slower non-spinning wheel(s).
I thought the transfer case was open too. Being able to transfer power either more to front or rear depending on wheel spin. Maybe I miss understood some information with you saying and power transfer is 50-50.
Thanks
My brother has a 2007 Avalanche with afm 5.3. It`s got 176,000 miles. Runs like a clock. Never been apart. Co worker has a 2010 Tahoe with afm 5.3. 230,000 miles. Never been apart. Runs like a clock. So, even though cyl deac is a weak spot, they can go the distance.
BUT, these engines had the oil changed regularly, AND had 5w30 as spec. I wonder if they would have lasted this far on 0w20? I`ll bet not.
