OK so i finally fixed my "Invalid Response from PCM" message. It turned out that the cable i got from ALDLcable was the problem got a new one from AKM and works fantastic. Anyway now i used the speed calibration utility to adjust for the gear change (2.73-3.73) and now the shifts are waaaaaay to late. Is there any thing else i need to change in the PCM when doing a gear change i.e. shift point mile per hour, i was thinking the speed calibration would take care of it.

 

Never mind figured it out

 

2.73/3.73 = .73

Multiply ALL your shift tables and your converter lock up tables by .73

 

I love it when people say "figured it out" and never tell anyone what it was. That is no help to the community.

 

Well i read the sticky on trans tunning and realized thats what i should have done first.
