2017 T43 cal file

[greasess]

I'm trying to find calibration #24275084 for a t43 controller. I haven't had any luck. The tune file drop box list doesn't have it. If anyone has it and is willing to post it that would really help me out.

The OS on the new t43 is 24254909 and this is the list of compatible trans OSs I found {24252573,24254909,24256025,24257135,24256065} The old t43 had OS 24276638.

It seems like the tcm gm sent us has an OS that isn't compatible with what the truck had.

If I'm missing something I would appreciate being clued in.
