- Shift solenoid D stuck in on position Very High
- Wiring short keeping solenoid D energized High
- Valve body bore allowing solenoid to stick open Moderate
- TCM commanding solenoid D on erroneously Low
Step-by-Step Diagnostic Procedure
-
Check if solenoid D remains energized when commanded off
-
Inspect wiring for short to power on solenoid D circuit
-

Frequently Asked Questions
Can I drive with code P0767?
Do not drive -- have the vehicle towed. Shift solenoid D stuck on 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.
