The torque converter clutch (TCC) connects the converter’s impeller with the turbine to mechanically lock the engine to the transmission. If the transmission control module (TCM) detects an issue with the TCC, the vehicle’s computer will log a P2764 code on a scan tool.
What Does the P2764 Code Mean?
Diagnostic trouble code (DTC) P2764 stands for “Torque Converter Clutch Pressure Control Solenoid Control Circuit Low.”
The torque converter acts as a clutch between the engine and the transmission, allowing the latter to be engaged even when the vehicle and wheels are stopped. It’s bolted to a thin metal disc called a flexplate, which lessens engine pulsations. The external ring gear on the flexplate engages the starter motor pinion gear to turn the engine when the vehicle is started.
All modern torque converters have a lockup clutch positioned between the turbine and front cover. The torque converter clutch (TCC) eliminates the energy-wasting slippage within the torque converter by creating a mechanical connection between the engine and the transmission.
Hydraulic fluid is used to apply the torque converter clutch. A computer—often referred to as the transmission control module (TCM)—looks at data from various sensors to determine when to apply the clutch. Once the TCM has deemed conditions are correct, it operates a solenoid valve to allow fluid flow to activate the converter clutch.
The Transmission Control Module (TCM) might set code P2764 if it notices that the torque converter clutch solenoid (or its circuit) isn’t operating properly.
Note: The definition of code P2764 might be different depending on the vehicle manufacturer. Consult the appropriate repair manual or repair database for the exact code definition.
What are the Common Causes of the P2764 Code?
- Faulty Torque converter solenoid
- Wiring issue
- Internal torque converter or transmission failure
- Issue with the TCM
What are the Common Symptoms of the P2764 Code?
- Illuminated check engine light
- Torque converter clutch doesn’t operate properly

How to Diagnose the P2764 Code
There are specific diagnostic steps to resolve the problems associated with DTC P2764. You’ll need to consult your vehicle’s repair manual to find the right fix for this code’s underlying issues. The following video can be used as a beginner’s guide to diagnosing a P2764. However, we recommend hiring a certified mechanic if you don’t have sufficient auto repair skills and knowledge for this particular task.
How to Fix the P2764 Code
Troubleshooting a P2764 code can be difficult because the solution can vary depending on the vehicle’s make and model. What might work to resolve a P2764 code for a Subaru might not work for a Honda. If you want to get started on troubleshooting this code, we recommend reading the Chilton repair manual to help you diagnose and repair your vehicle. There might be a technical service bulletin for your vehicle’s specific problems. You can also get an ALLDATA single-vehicle subscription to get more information on your vehicle and its potential problems.
