I am swapping a 5.3 and 6L80E into a 1968 Olds Cutlass. I am piecing together a combination of parts and have been able to read info off the PCM and TCM. My motor is 2011 my PCM is 2011 (OS=12639835) my TCM appears to be 09 (OS = 24249179). I am thinking the easiest way to get things to play together nicely is to change the TCM to a 2011 OS.

My question is can HPTuners do this, and will the TCM hardware support the newer OS?

Thanks,
Pat
