P0765Shift Solenoid D
- 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). P0765 is the general code for solenoid D and, at Ford, means an open circuit (0.5–5 s); shorts are P0982/P0983. On Ford's 6R80 and 6F transmissions solenoid D feeds either the low/reverse brake or the 4-5-6 clutch via a multiplex valve, on the 6R140 only the low/reverse brake; on the 2023 diesel its supply is shared with solenoid B and the converter clutch (P2669). A Ram 6.7 L bulletin traces P0765 to a leaking capacitor in the engine module.
