P0768Shift Solenoid D Electrical
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- A shift solenoid is an electrically switched valve in the valve body. Manufacturers use these codes differently: Ford reports an open circuit with the base code and shorts separately, and the letter is not tied to a valve number (Saab's Aisin 9-5: C = valve S4, D = valve S5). P0768 is the collective electrical code for solenoid D. GM's 2006 Allison tables flag a driver hardware fault for more than 0.1 s, after one trip; Saab's Aisin 5-speed (valve S5) checks current draw and enters limp mode with 'check gearbox'; Hyundai's 8-speed uses it for the valve of the 4 & overdrive clutch and replaces valve and electronic module, then the module if it returns. Ford does not use P0768.
