Truk is having problems and we want to rule the TCM out. Don't want to have to go through flashing it. But if it comes to it, then we will. Thanks.

Yep, same T42 for all years but E40 for 06 and E67 for everything else. You can flash an 08 TCM with an 06 TCM OS just fine, but DONT try that with the ECM (good news is neither HPT or EFILive will let you flash a controller with a file for a different controller).
