Torque Converter Clutch Apply Pressure Low
The P2759 code means the vehicle's onboard diagnostic system has detected: Torque Converter Clutch Apply Pressure Low. This is a moderate severity code.
- Keep driving?
- Short distances only
- DIY difficulty
- Advanced
- Estimated cost
- $200 - $2,500 (fluid change and solenoid to torque converter replacement)
Read and clear transmission codes. Many trans codes are caused by low or burnt fluid -- check level and color before assuming the worst.
Basic scanners only read engine codes. This reads transmission, ABS, and airbag too.

Common Symptoms
- Check Engine Light illuminated
- Shudder or vibration at highway speeds
- Poor fuel economy due to torque converter inefficiency
- Transmission overheating warning
- Harsh engagement or disengagement of torque converter lockup
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
Frequently Asked Questions
What does P2759 mean?
P2759 relates to the torque converter clutch (TCC) system: torque converter clutch apply pressure low. 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 P2759?
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 P2759?
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.

Step-by-Step Diagnostic Procedure
-
Scan for codes and confirm P2759 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
