I have a 1996 Chevy K3500 with the 5.7L and 4L80E
I have a P0713 Code. Last weekend I dropped the pan and installed a new internal wiring harness and TFT sensor. I put it all back together and that did not solve my problem. The transmission does not shift at the correct times, but when I clear the code, it shifts correctly. I checked the external wiring and the Wiring at the ECM. I do have a tuned ECM from blackbear. I am not sure what else could be causing this problem. Does anyone have any suggestions on what I could try or where else I could look?
