P2724

Pressure Control Solenoid "E" Stuck On

Severity: High
Driving: Drive only to a garage

Pressure control solenoid "E" is stuck on - applying pressure when it has been told not to. Line pressure will be higher than intended, so shifts become abrupt and the transmission may refuse to shift at all. Debris in the fluid holding the solenoid open is the usual reason.

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

Check whether the solenoid circuit is being held energised electrically before assuming a mechanical jam.
Very harsh shifts put shock loads through driveline components. Do not drive it like this any longer than necessary.
Check the fluid level and condition first. It is the cheapest check and it explains more transmission complaints than every electrical fault combined.
