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
