my M1165 won't shift up, or display codes when jumper wire used on the TCM...
Tried to do a 4L80-E TCM Diagnostic Code Retrieval (using a jumper wire) on my M1165. Another person with the same issue gave me that TM info, followed it exactly, but it's not working for my M1165 like it worked for his M1123. Different procedure?
Under drivers side rear seat, tried to jump A & E to get it to display codes and get it to reset to see if it will shift up, but the glow plug start light isn't blinking like it should after disconnecting the glow plug lead under the hood, and the trans light isn't blinking with code 12 either. It seems stuck in the low gear, rpms go up, but it won't shift up. Starts good. Runs good. Just won't shift into the higher gear. Max is 30mph with high RPMs. What am I doing wrong to get it to diagnose showing the codes? Here's a great video i watched as well, and followed it exactly step by step with same no results, no blinking lights...
Then this is a video of my results doing those exact steps...
