Hi Adam. My name is***** will try to help. What is the transmission model number from the transmission ID tag on the side of the case?

Thanks for the info Adam. Click on this link and let me know if you can pull any codes on the transmission.

Fault codes.

Customer: replied 1 year ago.

no codes

Expert:  Daniel Wilson replied 1 year ago.

Thanks for the info... Check for voltage to the transmission ECU ( TCM) and the harness for any damaged wiring and corrosion. Inspect your grounds. If ok check the filter and drain oil for metal/debris indicating an internal mechanical problem. Test the continuity of the switches and the harness. Let me know the results
