Shift Solenoid D Malfunction
The P0765 code means the vehicle's onboard diagnostic system has detected: Shift Solenoid D Malfunction. This is a critical severity code.
- Keep driving?
- No -- stop driving
- DIY difficulty
- hard
- Estimated cost
- $150 - $600 (parts and labor)
Read and clear transmission codes. Many trans codes are caused by low or burnt fluid -- check level and color before assuming the worst.

Common Symptoms
- Check Engine Light illuminated
- Transmission stuck in one gear
- Harsh shifting
- Limp mode activated
Probable Causes (Ranked by Likelihood)
- Failed D shift solenoid Very High
- Wiring issue in solenoid D circuit High
- Contaminated transmission fluid clogging solenoid Moderate
- TCM solenoid D driver fault Low
Step-by-Step Diagnostic Procedure
-
Measure shift solenoid D resistance -- typically 10-25 ohms
-
Command solenoid D with scan tool and listen for click
-
Inspect solenoid wiring at transmission connector
-
Check transmission fluid for contamination
-
Replace shift solenoid D if electrically or mechanically faulty
Common Fixes by Vehicle
What techs usually find when diagnosing P0765 on specific vehicles — tap your vehicle for the fix and the exact part:
2003-2015 Honda Accord/Odyssey Automatic Advanced DIY
Shift solenoid D on Honda automatics modulates TCC apply and release timing. A failing solenoid causes a shudder or flare during TCC apply at 40-55 mph. The solenoid is on the upper valve body. Replace it along with the other shift solenoids for a complete repair.
Labor: 2-4 hours2006-2018 Toyota RAV4/Highlander U250E/U151E Advanced DIY
Shift solenoid SL2 (solenoid D equivalent) on Toyota U-series transmissions has high failure rates in cold climates due to fluid viscosity issues. Use only Toyota WS ATF -- aftermarket fluids cause premature solenoid wear. Replace the solenoid and perform a complete fluid exchange.
Labor: 3-5 hours2005-2017 Nissan Pathfinder/Armada RE5R05A Advanced DIY
Solenoid D on the RE5R05A controls the 4-5 shift. The valve body bore for this solenoid wears out of spec causing the solenoid to leak pressure internally. A new solenoid in a worn bore will not fix the problem. Install a remanufactured valve body with oversized bore sleeves for a permanent repair.
Labor: 4-6 hoursFrequently Asked Questions
Can I drive with code P0765?
Do not drive -- have the vehicle towed. Shift solenoid D malfunction can cause the transmission to be stuck in the wrong gear or shift unpredictably.
What is shift solenoid D?
Shift solenoid D is an electro-hydraulic valve inside the transmission that controls fluid flow to engage specific gear combinations. It is commanded by the TCM to achieve proper shift timing.
Can I replace shift solenoid D without removing the transmission?
On most vehicles, shift solenoids are accessible by removing the transmission pan and sometimes the valve body. The transmission does not need to be removed from the vehicle.
