What shift solenoid E does depends on the transmission. On Ford's 6R80 and 6F35/6F55 it is an on/off valve that moves a multiplex valve, so solenoid D feeds either the low/reverse brake or the 4-5-6 clutch; on the 6R140 and 5R110W it is a proportional clutch valve with separate short codes (P0985/P0986). On Saab's Aisin 5-speed E is valve S1. P0772 is the counterpart of P0771: the gear ratio shows that the multiplex valve is stuck in its spring-loaded position (6R80/6F) or that the clutch controlled by solenoid E does not release (6R140: 4-5-6 clutch). Ford flags it after 10 or 3 events, continuously, and again counts valve, spool and clutch in; its 10R80 bulletins list it for harsh or delayed shifts. Harsh shifts, tie-up and a wrong gear follow.

Likely causes

Multiplex or shift spool sticking
Clutch plates stuck or burnt, piston hanging
Solenoid E stuck open
Contaminated fluid

Symptoms

  • Harsh shift jolt, transmission ties up
  • Limp mode in a fixed gear
  • Check engine light
