P0767 indicates the transmission control module has detected that shift solenoid D is not activating when commanded. This solenoid regulates hydraulic pressure to engage specific gears, often affecting higher gear shifts. The vehicle may enter a limp mode to prevent further transmission damage.
The solenoid coil may have an internal electrical failure or the valve may be mechanically stuck.
Low fluid level or debris in the transmission fluid can restrict hydraulic flow needed for operation.
Damaged wires or corroded connectors at the transmission can interrupt the control signal.
Debris blocking the valve body passages can prevent the solenoid from managing pressure correctly.
Worn internal components may create pressure leaks that mimic solenoid failure.
Internal failure of the Transmission Control Module is rare and should only be considered after other causes are ruled out.
It is not recommended as limp mode limits performance and continued driving may cause further damage.
Often no; the solenoid or fluid service may resolve the issue without full replacement.
No, control module failure is rare; diagnose the solenoid and wiring first.
No, the code will return until the underlying mechanical or electrical fault is repaired.
