P08CEShift Solenoid J Stuck On
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- Set when shift solenoid J is switched off but its clutch or shift valve stays applied, so the valve behaves as if stuck in its on position. No manufacturer documents this code publicly. GM's P0752 on the 6-speed transmissions is the nearest documented counterpart: with third gear commanded, the TCM flags shift solenoid A stuck on when the gearbox slip reaches 400 rpm while first or second gear is actually obtained, and the MIL comes on after one trip. Ford sets its stuck-on codes P0752 to P0772 from the gear or shift pattern actually reached. CARB requires such functional monitoring. P08CD is the opposite fault. Because an applied clutch can tie up the gearbox, drivers may feel a wrong gear, a harsh engagement or limp mode.
- What you may notice
- Check engine or transmission warning light on
- Wrong gear or harsh engagement, possible binding feel
- Transmission goes into limp mode
- Likely causes
- LikelySolenoid or its shift valve held in the applied position by debris or varnish
- PossibleContaminated transmission fluid after internal wear
- RareControl circuit shorted so the solenoid stays energised
- RareTCM output driver does not switch off
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
