P08CDShift Solenoid J Performance/Stuck Off
- 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 on but the gear or clutch it controls does not respond, so the valve behaves as if stuck in its off position. No manufacturer documents this code publicly. The closest documented analogue is GM's P0751 on the 6-speed transmissions: the TCM commands first gear and flags shift solenoid A stuck off when slip reaches 400 rpm with the gear ratio out of window, a two-trip fault. Ford sets P0751 to P0771 when the obtained gear or shift pattern shows a solenoid functionally failed off after three solenoid events. CARB requires this kind of functional check. P08CE is the opposite fault, P08CF and P08D1 to P08D4 cover the circuit. The driver notices slipping, flare or a missing gear.
- What you may notice
- Check engine or transmission warning light on
- Engine flare or slipping during or after a shift
- A gear is missing or skipped
- Transmission may hold a substitute gear
- Likely causes
- LikelySolenoid or its shift valve held in the off position by debris or varnish
- PossibleLow fluid level or weak supply pressure to the valve
- PossibleWorn clutch pack or leaking seal in the circuit served by the valve
- RareSolenoid coil too weak to move the valve
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
