System: Transmission

Diagnostic boundary

A diagnostic trouble code reports that a monitored test failed. It does not prove one specific part is bad, and manufacturer logic can add vehicle-specific conditions.

Do not replace the whole valve body without checking whether the stuck-on symptom is from wiring, debris, or a single solenoid.

Symptoms of P0762

Harsh, delayed, or slipping shifts, or being stuck in one gear.
Check-engine light, sometimes with limp-home mode.
Flaring RPM or a shudder under load.

Common causes of P0762

Low or degraded transmission fluid.
A failing speed sensor, shift solenoid, or pressure-control circuit.
Wiring, connector, or internal hydraulic/mechanical faults.

Useful checks before replacing parts

Monitor solenoid C command, actual gear, calculated ratio, input/output speeds, and pressure data during the failed shift.
Check for contaminated fluid, valve-body sticking, solenoid mechanical sticking, wiring shorts, or control-driver faults.
Look for companion incorrect-ratio or shift-timing codes that identify the affected gear path.
