The P2764 trouble code signals a deviation in the torque converter clutch pressure control solenoid circuit deviating.
The P2764 code is a standard OBD-II trouble code for the torque converter clutch pressure control solenoid circuit. The powertrain control module (PCM) uses the engine load and speed, as well as the vehicle speed and throttle position to select the needed torque converter clutch application (called “lock up”) degree. When the needed torque converter lock up deviates from the actual torque converter lock up, the P2764 trouble code may be triggered.
There are a few different mechanical issues that can trigger the P2764 code:
The P2764 code will usually be accompanied by the instrument panel’s Check Engine Light. The vehicle may have a problem with stalling when it reaches a full stop. The transmission may also slip, overheat, or have troubles shifting, and the vehicle may experience decreased fuel efficiency.
The P2764 code will first be diagnosed with a standard OBD-II trouble code scanner. A reputable technician should observe the freeze frame data available from the trouble code scanner, and will examine the P2764 code and check for any other trouble codes. Next, the technician will reset the codes and restart the vehicle, to see if the codes return. If the P2764 trouble code does not return following the reset, it is likely that the code was erroneously triggered.
If the code remains, the mechanic will start by checking the transmission fluid to make sure that it is clean and adequate. The mechanic will then move to the torque converter clutch to check for any issues with the wires or connectors.
The most common mistake made when diagnosing the P2764 trouble code is failure to follow the proper OBD-II trouble code diagnosis protocol. This can result in mistakenly searching for a mechanical issue when the trouble codes just need to be reset, or replacing the torque converter or torque converter clutch pressure control solenoid when only the wires or connectors needed replacement.
A car that is experiencing the P2764 trouble code can usually still be driven, though it will possibly experience transmission issues, and may stall with some regularity. Over time, this can result in serious damage to the transmission.
Some common fixes for the P2764 trouble code include:
If the PCM needs to be replaced (which is rarely the case), it will need to be reprogrammed upon installation.
