P0765: Shift Solenoid "D"
P0765 means the transmission computer has detected a general malfunction in shift solenoid D or its circuit, which can disrupt shifting into some gears.
Standard title per SAE J2012 / ISO 15031-6 · Updated 2026-11-07 · By CarWhere Research
How P0765 sets
On transmissions that use a fourth shift solenoid, the powertrain or transmission control module (PCM/TCM) monitors shift solenoid D's circuit while commanding it on and off. If the circuit response does not match the commanded state, it sets P0765. What solenoid D controls, and whether a transmission has one at all, varies by manufacturer.
Common causes of P0765
Roughly most likely first; the actual cause depends on the vehicle and needs testing to confirm.
- Failed shift solenoid D
- Wiring or connector problem in the solenoid D circuit
- Internal harness failure
- Low or contaminated fluid
- Valve body debris
- PCM/TCM fault (less common)
P0765 symptoms
- Check engine light on
- Limp mode
- Missing or skipped gears
- Harsh or delayed shifts
- Reduced fuel economy
How P0765 is diagnosed
- Check fluid level and condition.
- Scan all codes and review freeze frame data.
- Identify solenoid D's function for this specific transmission.
- Inspect wiring and the transmission connector.
- Measure solenoid D resistance and test circuit integrity.
- Command the solenoid with a bidirectional scan tool and road test.
Typical fixes for P0765
- Repair wiring or connectors
- Replace shift solenoid D or the solenoid pack
- Replace the internal harness
- Service the fluid and filter
- Repair or replace the PCM/TCM if confirmed
Replace parts only after testing confirms the cause — a code names the circuit or condition that failed a check, not necessarily the faulty part. We don’t publish per-repair prices; for what households actually spend on upkeep, see car repair costs.
Manufacturer notes
Shift solenoid D assignments vary by manufacturer and transmission; check factory service information.

P0765 FAQ
What does code P0765 mean?
P0765 means the transmission computer has detected a general malfunction in shift solenoid D or its circuit, which can disrupt shifting into some gears. The standard definition is "Shift Solenoid "D"."
Can I drive with a P0765 code?
Avoid extended driving. The transmission may lose gears or default to limp mode, and continuing to drive with improper shifting risks internal damage.
What does shift solenoid D do?
It is one of several solenoids that work together to select gears. Its exact job differs by transmission, so factory service information is the reliable reference.
Can a bad shift solenoid D cause harsh shifts?
Yes. If the solenoid fails to apply or release on time, shifts involving its clutch may feel harsh, delayed, or may not happen at all.

Manufacturers can add their own sub-definitions and test conditions; confirm with the factory service information for your year, make and model. Before paying for a repair, check NHTSA for open recalls and your warranty booklet: federal law requires an emissions warranty on major emission-control parts such as the catalytic converter and engine computer.
