What Does P2757 Mean?
The TCM has detected that the TCC pressure control solenoid is not responding properly to commands or is stuck in the off/disengaged position. The solenoid is either mechanically stuck, hydraulically blocked, or not producing the expected pressure range.
Common Causes
40%
TCC pressure control solenoid mechanically stuck in off position
25%
Valve body passages blocked with debris or clutch material
20%
Worn or damaged TCC pressure regulator valve in valve body
10%
Low line pressure due to worn pump or internal leaks
5%
Faulty transmission fluid pressure sensor providing incorrect feedback
Diagnostic Steps
1
Step 1: Monitor TCC solenoid duty cycle command and actual pressure response with scan tool during test drive
2
Step 2: Check for transmission fluid overfill or underfill conditions and inspect fluid quality
3
Step 3: Test solenoid operation by commanding TCC engagement/disengagement and monitoring RPM drop
4
Step 4: Measure line pressure with mechanical gauge at various operating conditions
5
Step 5: Remove transmission pan and inspect solenoid for debris, inspect valve body for scoring or damage
Estimated Repair Cost
$300 - $1,500
Parts + labor, varies by vehicle and location
The TCM has detected that the TCC pressure control solenoid is not responding properly to commands or is stuck in the off/disengaged position. The solenoid is either mechanically stuck, hydraulically blocked, or not producing the expected pressure range.
The most common cause of P2757 (Torque Converter Clutch Pressure Control Solenoid Control Circuit Performance/Stuck Off) is: TCC pressure control solenoid mechanically stuck in off position
Typical repair costs for P2757 range from $300 to $1,500, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Vehicle remains drivable but torque converter will not lock up, causing reduced fuel economy, increased transmission fluid temperatures, and potential long-term transmission damage.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2757 to identify the root cause.
