Transmission

P0761 — Shift Solenoid D Stuck On

Severity: medium Drive with care, to a shop

What P0761 means

The transmission control module (TCM) compares its command to shift solenoid D with the actual gear ratio and hydraulic response. The solenoid normally opens and closes fluid passages in the valve body so the right clutches apply and release. P0761 sets when solenoid D stays on, or stays open hydraulically, and the transmission does not respond as commanded.

Symptoms

  • Harsh or flared shifts
  • Missed or wrongly timed shifts
  • Slipping between gears
  • Transmission limp mode
  • Check engine light on

Possible causes

  1. Failed or sticking shift solenoid D
  2. Dirty, old or burnt transmission fluid clogging the solenoid
  3. Valve body wear or debris in the passages
  4. Damaged wiring or corroded transmission connector
  5. Faulty driver circuit inside the TCM
  6. Short or open in the solenoid wiring

How to diagnose

  1. Scan all codes and freeze frame data, and look for other transmission codes
  2. Check fluid level and condition: color, smell and metal particles
  3. Inspect the harness and transmission connector for damage, moisture and corrosion
  4. Measure solenoid D resistance and compare it with the manufacturer spec
  5. Check power, ground and the TCM control signal at the solenoid
  6. Use a scan tool to command the solenoid on and off and confirm it responds
  7. Drop the pan and inspect the magnet and filter for debris
  8. If needed, remove the valve body and inspect the solenoid and valves

Common fixes

  • Change transmission fluid and filter following the service procedure
  • Replace shift solenoid D
  • Repair the wiring harness or transmission connector
  • Clean or repair the valve body and replace worn parts
  • Repair or replace the TCM if its driver has failed

Questions and answers

What does code P0761 mean?

It means the transmission control module found shift solenoid D stuck in the on position. That can cause harsh or incorrect gear changes.

Can I drive with P0761?

Only briefly and carefully, to get to a repair shop. Slipping and limp mode speed up transmission wear, so don't put it off.

Will a fluid change fix P0761?

Sometimes, if the solenoid is sticking from dirt or old fluid. If the solenoid has failed or the wiring is damaged, you will need a repair or replacement.

This is general information about the code. The meaning can differ between makes and models: a scan tool and the repair manual for your car will show the exact cause.
