Shift solenoid D circuit fault.
How a shop works this
Work from evidence to part, not the other way round. A code names a circuit or a symptom; it does not name the part that failed.
Note every code that is set, not just this one.
Codes that appear together usually narrow the cause faster than any one of them read alone.
Read the freeze frame — the conditions the fault was recorded under.
Cold or warm, idle or load, road speed and engine speed. A fault that only appears cold is a different fault from one that only appears under load, even with the same code on the scanner.
Confirm the fault is current rather than history.
Clear the code and see whether it returns under those same conditions. A code that does not come back may have been logged during a repair, a flat battery, or a bad connection that has since been disturbed.
Then work the likely-causes list in the order shown.
That order is what a shop checks first for this code — wiring and connections before the component they run to, because a connector costs nothing to inspect and is a common answer.
If the code comes back after a repair, the underlying fault is still there. That is the point to bring in a scanner with live data and freeze-frame, or a shop that has one.

P0765 indicates an electrical fault in the Shift Solenoid D circuit, which on most 4-speed and 5-speed automatics controls overdrive engagement or torque converter clutch apply depending on application. The PCM has detected an open, short to ground, or short to voltage condition.
Begin with the cheapest checks
confirm the code is not a companion to a transmission internal harness failure (P0760 + P0765 together is a near-certain internal harness or case-connector fault), then unplug the external transmission connector and measure solenoid resistance pin-to-pin. Typical specs: 19 to 31 ohms on GM 4L60E shift solenoids, 9 to 16 ohms on Ford 4R75W, 11 to 15 ohms on Chrysler 45RFE solenoid pack, and 10 to 15 ohms on Toyota A340/A750 solenoids. Anything reading 0 ohms (short), infinite (open), or out of the spec band on a hot transmission confirms the solenoid. If the solenoid is in spec, back-probe the harness between the PCM/TCM and case connector for the proper 12V key-on and check for ATF migration up the wires (signs of greasy or stained insulation). Caveat: many transmissions share solenoid D between OD and TCC control, so a P0765 with a TCC-related symptom (no lockup, shudder) can also be caused by a failed TCC apply circuit in the valve body, not just the solenoid itself.

- 2000to 2005 Chevrolet Impala/Monte Carlo with 4T65E commonly sets P0765 from the 2-3 shift solenoid (designated D on this trans) failing electrically, with GM PI04132 calling for solenoid pack replacement.
- 2003to 2008 Dodge Ram 1500 with 45RFE/545RFE sets P0765 from the entire solenoid pack assembly failing, and Chrysler TSB 21-009-04 covers updated solenoid pack with revised screens.
- 2004to 2009 Toyota 4Runner/Tacoma with A750E/A750F flags the SL solenoid D code from internal valve body sleeve wear scoring the solenoid plunger.
- 2005to 2010 Ford Focus with 4F27E sets P0765 from the transmission range sensor or internal harness corrosion at the case connector pass-through.
Estimated repair$220 to $950.

P0765 — frequently asked
What does a P0765 code mean?
Shift solenoid D circuit fault.
What causes a P0765 code?
Common causes: Failed solenoid; Wiring.
What are the symptoms of a P0765 code?
Typical symptoms: Harsh shifts.
Is it safe to drive with a P0765 code?
Not for long. Driving on this one risks further damage. Get it to a shop rather than carrying on with it. Estimated repair: $200-$800.
How do I diagnose a P0765 code?
Work from evidence to part, not the other way round. A code names a circuit or a symptom; it does not name the part that failed. 1. Note every code that is set, not just this one. 2. Read the freeze frame — the conditions the fault was recorded under. 3. Confirm the fault is current rather than history. 4. Then work the likely-causes list in the order shown.
