Shift Solenoid E Stuck On
P0772 means Shift Solenoid E Stuck On. Learn the likely symptoms, causes, safety implications, and a practical diagnostic order.
What you may notice
Symptoms
- 01Check Engine or transmission warning light
- 02Harsh, delayed, or missing shifts
- 03Transmission stuck in one gear or fail-safe mode
- 04Possible overheating or reduced performance
Where to look first
Common causes
- 01Low, contaminated, overheated, or incorrect fluid
- 02Damaged solenoid wiring or connector
- 03Faulty shift solenoid or valve-body hydraulic problem
- 04Internal transmission or control-module fault
A sensible sequence
Best diagnostic order
- 01Save transmission and engine codes plus freeze-frame data
- 02Inspect fluid, leaks, connector, wiring, power, and ground
- 03Compare commanded gear, actual ratio, temperature, and solenoid state
- 04Perform electrical and hydraulic tests from service information
- 05Verify the repair through a controlled road test
Step by step
What to check and repair
- 01Check fluid condition and level using the correct procedure
- 02Inspect the transmission harness and connector
- 03Command the solenoid and test its circuit
- 04Confirm hydraulic and mechanical operation before major repair
Read the signals
Live-data clues
Commanded gear and solenoid state
- Typical behavior
- Actual ratio and shift response should agree with the command
- Possible clue
- A mismatch helps distinguish an electrical solenoid fault from hydraulic slip or mechanical damage
| Parameter | Typical behavior | What it can suggest |
|---|---|---|
| Commanded gear and solenoid state | Actual ratio and shift response should agree with the command | A mismatch helps distinguish an electrical solenoid fault from hydraulic slip or mechanical damage |
What P0772 means
P0772 is a generic OBD2 diagnostic trouble code. Its standardized description is “Shift Solenoid E Stuck On.” It identifies the circuit or operating condition detected by the control module, but it does not prove that a particular part must be replaced.
Diagnostic direction
Transmission codes need electrical, fluid, hydraulic, and mechanical checks. A solenoid code does not prove the solenoid itself is the only possible cause.
Before clearing the code
Save all stored and pending codes, freeze-frame data, and related module faults. Use vehicle-specific service information because connector locations, expected values, enable conditions, and repair procedures vary by make, model, engine, and year. Repair the verified cause before clearing the code, then repeat the appropriate self-test or drive cycle.
