P2764 GMC Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Issues with transmission shifting
P2764 Gmc DescriptionThe 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.
