4L80E in Limp Mode - Speartech Harness Issues
Hello, I am hoping somebody can help me. I have a 2000 Turbo Trans Am with a 4L80E that was originally a T56 car. The trans went into limp mode because the trans lost power from the PCM. However, I don't have the Speartech wiring diagram or instructions. Does anyone have a copy they could email me or text to me? I just have to verify which wire power comes from. Currently the car will only go into reverse and 2nd gear until I can figure out the wiring. Any help anyone can give me would be greatly appreciated. You can email the instructions to me at tmorales@wfwhelan.com or feel free to text me anytime at 313-790-5592.
Thanks.
Tony

This 4L80E wiring diagram might be useful:

Pin E on the trans needs to have +12V. I don't know what color that is on a Speartech harness, although I would suspect Red.
