Shift Solenoid E Electrical
The P0773 code means the vehicle's onboard diagnostic system has detected: Shift Solenoid E Electrical. This is a moderate severity code.
- Keep driving?
- Short distances only
- DIY difficulty
- hard
- Estimated cost
- $150 - $600 (parts and labor)
Read and clear transmission codes. Many trans codes are caused by low or burnt fluid -- check level and color before assuming the worst.
Basic scanners only read engine codes. This reads transmission, ABS, and airbag too.

Common Symptoms
- Check Engine Light illuminated
- Erratic shifting
- Possible limp mode
- Transmission may default to one gear
Probable Causes (Ranked by Likelihood)
- Open or short in shift solenoid E wiring Very High
- Failed solenoid E coil High
- Corroded transmission connector affecting solenoid E Moderate
- TCM solenoid E driver circuit failure Low
Frequently Asked Questions
Can I drive with code P0773?
Drive short distances only. Shift solenoid E electrical can cause the transmission to be stuck in the wrong gear or shift unpredictably.
What is shift solenoid E?
Shift solenoid E is an electro-hydraulic valve inside the transmission that controls fluid flow to engage specific gear combinations. It is commanded by the TCM to achieve proper shift timing.
Can I replace shift solenoid E without removing the transmission?
On most vehicles, shift solenoids are accessible by removing the transmission pan and sometimes the valve body. The transmission does not need to be removed from the vehicle.
