A torque converter clutch pressure control solenoid allows the ECU to control the operation of the torque converter clutch by manipulating the flow of pressurized transmission fluid. If a low voltage signal is detected, a P2764 DTC will be stored.

How Serious is the Code?
In terms of severity, a P2764 diagnostic trouble code is quite serious because it means the ECU is having trouble engaging and disengaging the TCC clutch. Some of the transmission problems you may experience include engine stalling, transmission overheating and erratic shifting.
Symptoms
Symptoms of a P2764 include:
- Harsh, erratic shifts
- Slipping
- Engine stalls while stopped in gear
- Vehicle won’t move when in gear
- Increased fuel consumption
- Transmission overheats
- Limp mode
Causes
- Insufficient transmission fluid
- Dirty transmission fluid / filter
- Frayed wiring / damaged connectors
- Transmission fluid leak
- Failing torque converter clutch pressure control solenoid
- Failing torque converter
- Failing torque converter clutch
- Internal pressure problems
- Valve body issue
- ECU or TCM failure\
How to Diagnose the Code?
The first step to diagnosing a P2764 OBDII trouble code, is checking the level and condition of the transmission fluid. Checking the wiring and connectors for signs of damage and corrosion should also be done. If everything looks good, the TCC pressure control solenoid will have to be checked.
