What P0773 means
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. P0773 is the electrical code for solenoid E. GM's 2006 Allison tables flag a driver hardware fault for more than 0.1 s, cross-checked by pressure switch E, after one trip; Saab's Aisin 5-speed checks the current of valve S1 with fluid above 20 °C and shows 'check gearbox'; Hyundai/Genesis 8-speeds use it for clutch valve E and replace valve and electronic module. Ford does not use P0773.

Symptoms of P0773
- Transmission warning or check engine light
- Limp mode in a fixed gear
- Harsh shifts
Common causes of P0773
- Most likelyOpen or corroded wire or transmission connector
- PossibleSolenoid coil faulty
- PossibleTransmission module or electronic module faulty
- Less likelySolenoid supply missing
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0773 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 7 | Area: transmission. |
| 73 | The exact fault in that area. |
What to do next
- Note P0773 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0773
What does P0773 mean?
P0773 means "Shift Solenoid E Electrical". What shift solenoid E does depends on the transmission. It is a generic code, so it means the same on every make.
Is it safe to drive with P0773?
Drive gently and only to a workshop. With P0773 the car can go into limp mode (reduced power) to protect itself.
Will P0773 fail an emissions test?
Yes, it can. P0773 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P0773 to fix?
Difficulty: medium. A typical repair takes 1 to 5 hours of work. This is a job for a workshop.
Will P0773 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
