What Does P2763 Mean?
The transmission control module (TCM) has detected an abnormally high voltage in the torque converter clutch pressure control solenoid circuit. This indicates a potential short to voltage, open circuit, or internal solenoid failure preventing proper lockup control.
Common Causes
35%
Shorted or damaged wiring harness between TCM and TCC solenoid
30%
Failed torque converter clutch pressure control solenoid (internal short)
20%
Corroded or damaged electrical connector at solenoid
15%
Failed transmission control module (TCM)
Diagnostic Steps
1
Step 1: Inspect transmission external wiring harness and TCC solenoid connector for damage, corrosion, or pinched wires
2
Step 2: Disconnect TCC pressure control solenoid connector and measure resistance across solenoid terminals (typically 3-30 ohms depending on manufacturer)
3
Step 3: Check for short to voltage by measuring voltage at harness side of connector with key on, engine off (should read 0V)
4
Step 4: Perform continuity test on wiring between TCM and solenoid to identify opens or shorts
5
Step 5: If wiring and solenoid test normal, substitute known-good TCM to verify module failure
Estimated Repair Cost
$200 - $1,200
Parts + labor, varies by vehicle and location
The transmission control module (TCM) has detected an abnormally high voltage in the torque converter clutch pressure control solenoid circuit. This indicates a potential short to voltage, open circuit, or internal solenoid failure preventing proper lockup control.
The most common cause of P2763 (Torque Converter Clutch Pressure Control Solenoid Control Circuit High) is: Shorted or damaged wiring harness between TCM and TCC solenoid
Typical repair costs for P2763 range from $200 to $1,200, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Vehicle may experience harsh shifting, poor fuel economy, or inability to achieve torque converter lockup. Generally safe to drive short distances but may cause transmission overheating with extended use.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2763 to identify the root cause.
