Anyone have the stock file for a 2011-2012 Silverado with the updated OS to correct the crappy shifting issues? Truck I bought had a really bad tune and the repository tunes I found bricked my old TCM. Starting over and want the proper software! Thanks!
Wouldn't the dealership that flashed the TCM to your VIN have done that for you?
That flash would have been the most up to date if a dealership did it.
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
If you don't post your tune and logs when you have questions you aren't helping yourself.
