Hello, new expert here. The P0785 code sets when there is a problem with the 3-2 downshift solenoid circuit in the transmission. The fix will be to inspect the wiring and replace the 3-2 solenoid. The transmission pan must be removed to replace this solenoid. Refer to attached image for location of the solenoid.
