- Faulty Torque Converter Clutch Pressure Control Solenoid
- Torque Converter Clutch Pressure Control Solenoid harness is open or shorted
- Torque Converter Clutch Pressure Control Solenoid circuit poor electrical connection
- Clogged valve body oil passages
How do I fix code P2764 CADILLAC?
Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins.
Cost of diagnosing the P2764 CADILLAC code
The cost of diagnosing the P2764 CADILLAC code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.
When is the code detected
When the Transmission Control Module (TCM) detects a continuous open or short to ground in the Torque Converter Clutch Pulse Width Modulated (TCC PWM) Solenoid valve circuit, then the P2764 code sets.
Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Issues with transmission shifting
P2764 CADILLAC Description
The Transmission Control Module (TCM) provides voltage to the Torque Converter Clutch Pulse Width Modulated (TCC PWM) solenoid valve through High Side Driver 2 (HSD2). The TCM controls the ON and OFF time of the solenoid by providing a ground through the output driver module (ODM). The TCM uses a PWM duty cycle, in order to control application and release of the TCC. When the solenoid is commanded OFF, the TCM senses high voltage. When the solenoid is commanded ON, the TCM senses low voltage.
