P2757: Torque Converter Clutch Pressure Control Solenoid Control Circuit Performance/Stuck Off
The TCC pressure control solenoid is commanded on but does not produce the expected lockup pressure. TCC stays open or partially engaged.
What P2757 means
P2757 is a generic OBD-II powertrain code in the transmission group. In plain English: the signal is within electrical limits but doesn’t make sense compared with other readings, so the part or system isn’t performing as expected.

Symptoms
- Check engine or transmission warning light on
- Harsh, delayed, or missing shifts
- Possible limp mode (locked in one gear)
- Slipping or shuddering during gear changes
Common causes
- 01Solenoid spool stuck in closed positionMost likely
- 02Hydraulic feed restricted by debrisPossible
- 03Carbon or debris buildup preventing free movementLess likely
Can I drive with P2757?
Usually yes, for a short time.
The car will often drive normally, but get it diagnosed soon. If you notice rough running, warning lights flashing, overheating or a burning smell, stop driving.
Why we rate it moderate
- Turns on the check engine light
Severity is our rule-based rating from the code’s flags in OBDex and the system it affects, not an inspection of your car. If the check engine light is flashing, or you notice overheating, low oil pressure, or brake or steering problems, stop driving and get help.
How to diagnose P2757
- 1
Confirm the code and save freeze-frame data
Read the codes with an OBD-II scan tool and note every code, not just P2757. Save the freeze-frame data (speed, load, temperature when the fault set) before clearing anything; it tells you when the fault happens.
- 2
Fix other faults first
If other codes are stored, start with power-supply, sensor-circuit and communication codes. They can cause this code as a side effect.
- 3
Test the circuit
Inspect the wiring and connector at the tcc pressure solenoid and torque converter for damage, corrosion or chafing. With a multimeter, check supply voltage, ground and signal against the specifications in the service manual for your vehicle.
- 4
Test the likely causes in order
Start with the most likely cause and work down: Solenoid spool stuck in closed position; hydraulic feed restricted by debris; carbon or debris buildup preventing free movement. Test before replacing parts.
- 5
Check for recalls and service bulletins
Look up recalls for your exact vehicle with its VIN, and ask a dealer about technical service bulletins (TSBs). Manufacturers sometimes issue software updates or extended warranties for known faults.
- 6
Clear the code and verify the repair
After the repair, clear the code and drive the car under the conditions in the freeze-frame data to confirm it does not return.

P2757 FAQ
What does P2757 mean?
P2757 means “Torque Converter Clutch Pressure Control Solenoid Control Circuit Performance/Stuck Off”. The TCC pressure control solenoid is commanded on but does not produce the expected lockup pressure. TCC stays open or partially engaged.
Is P2757 serious? Can I keep driving?
We rate P2757 as moderate severity. Usually yes, for a short time. The car will often drive normally, but get it diagnosed soon. If you notice rough running, warning lights flashing, overheating or a burning smell, stop driving.
What causes P2757?
The most common causes, from most to least likely: Solenoid spool stuck in closed position; Hydraulic feed restricted by debris; Carbon or debris buildup preventing free movement. Test before replacing parts, because several causes can set the same code.
How much does it cost to fix P2757?
Typical labor is about $250–$1,000 at an assumed $125/hour shop rate, plus parts. That is an estimate, not a quote: labor times and rates vary by vehicle and region, and diagnosis may be billed separately.
Can I fix P2757 myself?
DIY difficulty is hard. Most owners leave this to a shop because it needs involved testing or specialist tools. Always confirm the cause before buying parts.
Will P2757 clear itself?
If the fault was intermittent, the warning may go off once the computer stops seeing it, but the code stays in memory. Fix the cause; clearing the code alone doesn’t repair anything.
