P2717

Pressure Control Solenoid "D" Intermittent

Severity: High
Driving: Drive only to a garage

The circuit for pressure control solenoid "D" is faulting intermittently. The transmission may drive normally for long periods and then shift harshly or drop into limp mode, recovering after a restart.

Possible causes

CommonDebris in the fluid jamming the solenoid
CommonFailed solenoid
CommonCorroded transmission case connector, or fluid wicking into it
CommonLow or degraded fluid
PossibleInternal transmission harness failure
PossibleSticking valve in the valve body bore

What you might notice

Very harsh or violent shifts
Slipping under load
Transmission stuck in one gear
Delayed engagement into drive or reverse
Check engine light on

What to check, in order

Note whether it only happens hot - that points strongly at the internal harness or the solenoid itself.
Record the freeze frame data if the tool supports it.
Check the fluid level and condition first. It is the cheapest check and it explains more transmission complaints than every electrical fault combined.
