The torque converter is designed to transfer power from the engine to the transmission, and the torque converter clutch locks the two together in order to improve efficiency and performance. The torque converter clutch pressure control solenoid provides the hydraulic pressure needed to engage and disengage the clutch. If the ECU detects unusually high voltage coming from the solenoid control circuit, a P2763 DTC will be set.

How Serious is the Code?
The P2763 diagnostic trouble code is pretty serious, because it means the vehicle’s computer can’t control the operation of the TCC clutch. Some of the symptoms you may experience include slipping, delayed shifts and engine stalling.
Symptoms
Symptoms of a P2763 include:
- Erratic, delayed or harsh shifts
- Transmission slipping
- Engine stalls when coming to a stop
- Transmission gets stuck in a gear
- Vehicle won’t move when in gear
- Lower MPG
- Transmission overheats
- Limp mode
Causes
- Low transmission fluid
- Dirty transmission fluid / filter
- Frayed wiring / damaged connectors
- Transmission fluid leak
- Failed torque converter clutch pressure control solenoid
- Failed torque converter clutch
- Failed torque converter
- Pressure blockage
- Valve body issue
- TCM or ECU failure
How to Diagnose the Code?
Having low or dirty transmission fluid can affect the operation of the torque converter clutch pressure control solenoid, so that should be the first thing to check when diagnosing a P2763 OBDII trouble code. The wiring and connectors should also be checked for damage. If everything looks good up to this point, the TCC pressure control solenoid will have to be tested directly.
