Hello new here and new to tuning.
I am working on a Saab 97x (trailblazer) so I swapped a 4l60e to a 4l80e. I bought an adapter harness to relocate pin location from the 4l60e to 4l80e and not the relay style. I have tried serval different so swaps on the TCM. The problem is the gear selector still reads first gear no matter what and will not communicate with the ECM throw's a code u0101 lost communication with TCM. i will try to put my latest file any help would be greatly appreciated. here are two different files I have tried.
