The P0762 code in your 2019 Chrysler 300 indicates that shift solenoid C is stuck in the on position. This is the opposite of P0761—the solenoid is continuously activated when it should be able to turn off. Your 300 uses the ZF 8HP automatic where this causes specific gear selection conflicts.
Shift Solenoid C Stuck On Effects
When solenoid C is stuck on, the hydraulic circuit it controls remains engaged continuously. This can cause the transmission to have difficulty with certain gear combinations that require solenoid C off. Gear conflicts and incorrect ratios may result.
Common Causes
A mechanically stuck solenoid that won't return to off. Valve stuck in the applied position due to debris or wear. Electrical short keeping the solenoid energized. Valve body issues trapping the solenoid valve. Spring failure inside the solenoid preventing return.
Symptoms in Your 300
The transmission may have difficulty with certain gear changes. Shifts may feel conflicted or harsh in specific gear ranges. The transmission may skip gears to avoid conflicts. Possible gear ratio error codes alongside P0762. Check engine light illumination.
Chrysler 300 Diagnosis
Using Chrysler wiTECH, monitor shift solenoid C state versus commanded state. Check for gear conflicts when solenoid C should be off. Test solenoid valve movement—it should move freely when de-energized. Inspect valve body for stuck valves. Check ZF 8HP fluid level and condition.
