Order of inspection
P0787 Shift/Timing Solenoid Low Medium
The P0787 code means the control circuit of the shift/timing solenoid shows low voltage, either a short to ground or a lack of power. It is an electrical fault, so check the transmission connector and wiring before you replace the solenoid. The transmission can shift harshly or drop into limp mode.
