What P0765 means
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.
P0765 at a glance

- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium
- Typical labor0.5 to 4 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0765
- Check engine or transmission warning lamp
- Limp mode in a fixed gear (Ford: fifth with maximum pressure)
- No reverse or engine braking in first, or missing 4th–6th gears (Ford)
Common causes of P0765
- Most likelyOpen or corroded wire, connector or internal harness
- PossibleSolenoid coil open or shorted
- Less likelySolenoid supply (high-side switch) missing
- Less likelyModule driver faulty
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0765 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 7 | Area: transmission. |
| 65 | The exact fault in that area. |
What to do next
- Note P0765 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0765
What does P0765 mean?
P0765 means "Shift Solenoid D". A shift solenoid is an electrically switched valve in the valve body. It is a generic code, so it means the same on every make.
Is it safe to drive with P0765?
Drive gently and only to a workshop. With P0765 the car can go into limp mode (reduced power) to protect itself.
Will P0765 fail an emissions test?
Yes, it can. P0765 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P0765 to fix?
Difficulty: medium. A typical repair takes 0.5 to 4 hours of work. This is a job for a workshop.
Will P0765 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
