По ошибке могу сказать только из техдока:
P0765/65 S4 SOLENOID VALVE MALFUNCTION
The ECM uses signals from the vehicle speed sensor to detect the actual gear range (1st, 2nd, 3rd or O/D gear). Then the ECM compares the actual gear with the shift schedule in the ECM memory to detect mechanical troubles of the shift solenoid valves and valve body
Trouble Area:
- Shift solenoid valve S4 is stuck open or closed
- Valve body is blocked or stuck
