Unusual Issue with a 2006 Vette. Attached is the Tune pulled from the Computer.
Problem is HPtuners cannot identify Trans Controller,

So I manually input T43 GM A6, the trans compatible in on this car.

Tune pulls up fine and can change the values. Tune compares to other Stock tunes pulled from 2006 A6 Vette's.
Flashing back into the PCM/TCM has no errors and issues.
Once I'm out on the road driving, the Trans is stuck in one gear and in limp mode, shifting down to sport mode and choosing gear the heads up display shows random gears changing from 2 to 5, TCM is confused, obviously the wrong TCM parameters are input/flashed into the TCM.
Any attempt to read actual controller in car has failed, in both ACC/and Ignition mode on.
Don't want to take the car to the Dealer to re-flash a stock tune. Hope someone can help.
Thank you !
