P287A means clutch B stays closed, or keeps transmitting torque, at a moment when it should be open. Ford lists P287A as an MIL code in its 2014 code catalogue. In the DPS6 gearbox Ford describes for 2012, clutch B carries reverse together with 2nd, 4th and 6th and is pushed open by a return spring once its electric motor backs off; the older summary books that motor case as P07A5. Mitsubishi's 2023 Outlander PHEV flags the clutch A counterpart P2872 if a clutch meant to be open shows a slip of 8 rpm at most for 3.5 s while the front motor spins at 750 rpm or above. Applied to clutch B, the result is two clutches pulling at once: shudder, a strong pull in neutral or a stalled engine at a standstill. The TCM normally locks out the affected half of the gearbox.

Likely causes

Clutch B actuator or return spring not opening the clutch
Clutch B plates seized or welded after overheating
On wet systems a valve held in the apply position by debris
Control unit or wiring commanding apply continuously

Symptoms

  • Shudder or binding, strong pull in neutral
  • Engine stalls when the car stops
  • MIL on, gears locked out
