P07DFIncorrect Shift from Gear 4
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- The series 'Incorrect Shift from Gear N' (P07DC–P07E3 for gears 1–8, P07FA and P07FD for 9 and 10) covers a shift that leaves the starting gear but lands in a gear other than the commanded target – a skipped or overshot gear. A module can see this after the shift because the measured ratio matches the wrong gear. No manufacturer document available to us uses the series: Ford assigns such patterns to the shift solenoid that caused them (P0751 ff), newer GM automatics report clutch pressure valve codes. P07DF starts from gear 4. It differs from P0734 (wrong ratio while in gear 4, a slipping clutch), P072F (gear 4 cannot be left) and P0784 (the shift itself takes too long or flares). Detection, MIL and trip count therefore follow only by analogy from CARB's functional check and Ford's ratio and shift completion checks.
