P0770Shift Solenoid E

  • Generic OBD-II code · Powertrain
  • Turns on the check-engine light
  • Matters for the ITP
  • Can trigger limp mode
How the car detects it
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. P0770 is the general code for solenoid E; Ford uses it for an open circuit, detected when the smart driver feedback disagrees with the command for 0.5–5 s, and on the 6R80/6F it covers all circuit faults of the solenoid. On Ram's 6.7 L with Aisin AS69RC a 2023 bulletin traces P0770 to a leaking capacitor in the engine module, together with other circuit codes. Limp mode follows; on the 6R80/6F engine braking in first or the 4th–6th gears may be missing.
What you may notice
  • Transmission warning or check engine light
  • Limp mode in a fixed gear
  • Harsh shifts
Likely causes
  • LikelyOpen or corroded wire or transmission connector
  • PossibleSolenoid coil faulty
  • PossibleTransmission module or electronic module faulty
  • RareSolenoid supply missing
Inspection (ITP)
Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
