I used a Motech Swap Kit with their Harness, ECU, and tune.
Engine runs good in park However when I try and shift it out of park it revs immediately to WOT on its own and does not engage gears.
Here is the ECU and TCM info. I checked on TIS2web and the TCM OS system seems to be correct for the VIN.
Trying to determine where to go next with this. Reprogram TCM, More Tuning, Wiring Pin out issue, Etc as this is going to get very expensive very quickly.
Any help would be greatly appreciated
