P2762 indicates that the PCM has detected a performance problem in the torque converter clutch (TCC) pressure control solenoid circuit, meaning the solenoid is not delivering pressure within the expected range.
The solenoid may be internally failed or have excessive wear, preventing proper pressure modulation.
Dirty fluid can restrict pressure flow to the solenoid, causing out‑of‑range readings.
Corroded pins, broken wires, or poor connections can produce resistance or open circuits that affect solenoid performance.
A bad sensor can give inaccurate pressure data to the PCM, triggering the code.
Only after all hardware has been verified should a PCM defect be considered, as it is an uncommon cause.
It is possible but extremely uncommon. Most cases are due to the solenoid, fluid, wiring, or sensor. Replace the PCM only after all other possibilities are ruled out.
A reset may turn off the light temporarily, but if the underlying issue (e.g., bad solenoid or fluid) remains, the code will return.
The vehicle can usually be driven, but you may experience reduced fuel economy, shuddering, or stall risk. It is advisable to diagnose and repair promptly.
A standard digital multimeter for resistance checks and a scan tool capable of reading live transmission data are sufficient for most diagnostics.
