P2704Transmission Friction Element E Apply Time Range/Performance
- 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
- P2704 is stored when friction element E takes too long or too short a time to apply, judged against the speed change the controller expects for the shift. Ford bulletins tie the code directly to the E clutch. TSB 23-2376 describes F-550/F-600 trucks of model year 2022 with the 6.7L diesel and 10R140: once they have covered over 8,000 km the input shaft wears against the E clutch hub, its O-rings fail and the E clutch circuit loses pressure, so P2704 appears with P0771 and the wrench lamp; hub and O-rings are renewed. On the 2020 Transit with the 10R80, TSB 20-2185 links P2704 and P0772 to harsh engagement into drive from sticking valves. Land Rover's SSM71847 lists P2704-07 among ZF 9HP48 faults on 2014-15 Evoque and Discovery Sport.
