4L80 conversion--2005 GTO Did anyone that converted to a 4L80 get their speedo and cruise to work?
My issues:
I swapped from T56 to 4L80 and changed out the engine/trans wiring harness to a A4 harness. I have the PCMforless conversion plug and relays. They also supplied a T42 and put the A4 tune in my computer.
(1)Speedo is way fast, 40mph shows about 85mph. The VSS plug is plugged into the rear sensor.
(2) still have to depress he clutch switch to get it to start.
(3)No cruise control.
Thanks for any ideas!
