P0752
Shift Solenoid "A" Stuck On
- Severity
- High
- Driving
- Drive only to a garage
Shift solenoid "A" is stuck on - applying when it should be released. Because the gear it controls stays engaged, the transmission can end up trying to hold two gears at once, which it will not tolerate: expect very harsh behaviour, a refusal to shift, or a stall as the car slows.
Possible causes
- CommonDebris jamming the solenoid open
- CommonFailed solenoid stuck in the applied position
- CommonSticking valve in the valve body
- PossibleDegraded, varnished fluid
- PossibleWiring fault holding the solenoid energised
What you might notice
- Very harsh shifts or a bang on engagement
- Transmission will not shift out of one gear
- Engine stalls when coming to a stop
- Binding or dragging feeling when moving off
- Check engine light on
What to check, in order
- If the engine stalls as you come to a stop, treat it as urgent - losing the engine means losing power steering and brake assistance at a junction.
- Check whether the solenoid circuit is being held energised electrically. A shorted wire mimics a jammed solenoid exactly and is far cheaper to repair.
- Check the fluid level and condition, and look for debris.
- Read all codes. Several stuck solenoids point at contaminated fluid affecting the whole valve body.
- Do not drive it far in this state. Two gears trying to engage at once puts very high loads through the transmission internals.
