Common Symptoms

Check Engine Light illuminated
Shudder or vibration at highway speeds
Poor fuel economy due to torque converter inefficiency
Transmission overheating warning
Noticeable vibration between 35-50 mph during light throttle

Probable Causes (Ranked by Likelihood)

Worn torque converter clutch friction material High
TCC solenoid failure or contamination High
Degraded or contaminated transmission fluid Medium
Valve body TCC circuit wear or debris Medium
TCM/PCM calibration issue Low

Step-by-Step Diagnostic Procedure

Scan for codes and confirm P2765 with freeze frame data
Check transmission fluid level, condition, and mileage since last change
Monitor TCC slip speed, apply pressure, and temperature PIDs during road test
Test TCC solenoid resistance and operation with scan tool bidirectional control
Check for updated TCM/PCM calibration (TSBs) for your vehicle

Frequently Asked Questions

What does P2765 mean?

P2765 relates to the torque converter clutch (TCC) system: torque converter clutch shudder detected. The TCC locks the torque converter at highway speeds for fuel efficiency, and this code indicates a problem with that system.

Can I drive with P2765?

You can drive short distances but expect reduced fuel economy and possible shudder. Have it inspected to prevent torque converter damage.

How much does it cost to fix P2765?

Costs range from $200 for a fluid change (if contamination is the cause) to $2,500 for torque converter replacement. TCC solenoid replacement is typically $300-$800.
