P276E Electric/Auxiliary Transmission Fluid Pump B Motor Current Low

Check engine lightOn
EmissionsNot relevant
Drive cycleNot required
Limp modePossible

P276E tells you that the motor of a second electric transmission fluid pump, called B, takes less current than its commanded duty would require. A small draw usually means the motor is not really working: a broken winding, worn brushes, extra resistance in the feed or ground, or an impeller spinning freely because it has no fluid to move. No manufacturer documents P276E publicly. Ford shows the same check for pump A in its 2024 OBD summary for the 10R60/10R80 and 8F57 gearboxes, where an under-current reported by the pump becomes P0C27 (UDS P0C26_18). What pump B is depends on the car; Audi names the gear oil pump V553 on its 0CJ, 0CK and 0CL twin-clutch units. P276F covers the opposite case. Expect stop-start to be withheld while the fault is present.

Likely causes

Worn brushes or open winding in the pump B motor
Corroded connector or high-resistance feed/ground to the pump
Low fluid level so the impeller runs without load
Faulty current measurement in the pump controller or TCM

Symptoms

  • Check engine or transmission warning lamp
  • Engine stop-start no longer operates
  • Delayed or harsh drive engagement after an engine restart
