What Does P0762 Mean?
The Shift Solenoid B electrical circuit or the 2-3 shift solenoid circuit has an electrical fault. The TCM has detected an abnormal voltage condition such as an open circuit, short to ground, or short to battery in the solenoid B wiring. This prevents the TCM from properly controlling the solenoid, affecting gear shift transitions.
Common Causes
35%
Open or short circuit in the shift solenoid B wiring harness
30%
Shift solenoid B internal coil failure
20%
Corroded or damaged transmission connector pins
10%
TCM solenoid driver circuit failure for solenoid B
5%
Ground circuit issue for the solenoid pack
Diagnostic Steps
1
Measure shift solenoid B resistance at the transmission connector — open or near-zero resistance indicates coil failure.
2
Check for voltage supply and TCM drive signal at the solenoid B pins with the key on.
3
Inspect the external transmission harness connector for corroded, bent, or damaged pins.
4
Perform continuity and short-to-ground tests on the solenoid B circuit wiring from TCM to transmission.
5
If wiring checks pass and solenoid resistance is out of specification, replace solenoid B.
Estimated Repair Cost

The most common cause of P0762 (Shift Solenoid B Electrical/ 2-3 Shift Solenoid Circuit Electrical) is: Open or short circuit in the shift solenoid B wiring harness
Typical repair costs for P0762 range from $150 to $900, depending on the vehicle, location, and whether you do it yourself or go to a shop.
The transmission will likely enter limp mode with limited gear availability. Driving at low speed to a repair facility is safe, but normal driving should be avoided until repaired.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P0762 to identify the root cause.
