P27CE Pressure Control Solenoid R Control Circuit Range/Performance
P27CE would be stored if the control circuit of solenoid R stayed electrically connected yet produced values that make no sense to the controller. No manufacturer documents this code publicly. On the Corvette dual-clutch transmission GM checks valve 4 for a mismatch between commanded and estimated current (over 70 % for 60 ms, or 400 mA for 300 ms in 23OBDG07), but that check reports P27D0. Ford's 2024 list for the TR9070 likewise offers only open load, shorted load and shorted switch for SPV4. CARB 13 CCR 1968.2 sets the general monitoring duty. Typical reasons would be rising contact resistance, a solenoid with partly shorted turns, or a weak TCM driver output.
Likely causes
Symptoms
- MIL on
- Shift feel varies on rods 3 and 4
Repair estimate
Typical range across vehicles; the real cost depends on what the testing finds.
