P27F3 Clutch B Temperature Too High

P27F3 reports that the second clutch of a gearbox, usually the clutch on the even-gear side of a dual-clutch unit, has exceeded its permitted temperature, either measured or calculated from slip and load. Stellantis is the one maker with a public, code-exact document: bulletin 21-040-26 (May 2026) lists P27F3-00 as clutch 2 overtemperature on European 2022-2025 Jeep Renegade and Compass with the 1.5 L mild hybrid and the 7HDT300 dual-clutch box. The MIL is lit, and gear groups or reverse may become unavailable. Particles that block a pump in the electric clutch actuator are named as the cause, and the actuator cylinder is replaced. P2787 is the same verdict for clutch A. Repeated creeping or hill starts make it worse.

Likely causes

Pump in the electric clutch actuator blocked by particles
Long slipping phases from creeping, towing or hill starts
Worn clutch 2 that needs more slip to transmit torque
Insufficient clutch cooling or low or aged fluid

Symptoms

  • Malfunction indicator and transmission warning lamp on
  • Even gears or reverse temporarily unavailable
  • Judder or burning smell when pulling away
