What P2756 means
P2756 is the base code for the solenoid that meters apply pressure to the torque converter clutch. On its own it names only the component; in UDS-based systems a failure-type byte says what went wrong. Toyota shows this use in bulletin T-SB-0160-18 for the 2017–2018 Highlander and Sienna with the eight-speed automatic: P27567F, a stuck-off result for the lockup pressure solenoid, is one of eleven transmission codes that justify a remanufactured transaxle when a whine, harsh shifts or reduced power accompany it. The more specific siblings P2757 to P2764 split the same component into functional and electrical faults. For the driver a fault here typically means no or unstable converter lockup, higher engine speed at cruise and more heat in the fluid.
P2756 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyHard
- Typical labor1 to 10 hours
- Clears after repairAfter a drive cycle
Symptoms of P2756
- Converter lockup missing or unstable
- Higher engine speed and fuel use at steady speed
- Whine noise or harsh shifts (Toyota 8-speed)
Common causes of P2756
- Most likelyInternal transmission damage or debris in the valve body (Toyota 8-speed)
- PossibleLockup pressure solenoid sticking or worn
- Less likelyWiring or connector fault on the solenoid circuit
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2756 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 7 | Area: transmission. |
| 56 | The exact fault in that area. |
What to do next
- Note P2756 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2756
What does P2756 mean?
P2756 means "Torque Converter Clutch Pressure Control Solenoid". P2756 is the base code for the solenoid that meters apply pressure to the torque converter clutch. It is a generic code, so it means the same on every make.
Is it safe to drive with P2756?
Drive gently and only to a workshop. With P2756 the car can go into limp mode (reduced power) to protect itself.
Will P2756 fail an emissions test?
Yes, it can. P2756 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P2756 to fix?
Difficulty: hard. A typical repair takes 1 to 10 hours of work. This is a job for a workshop.
Will P2756 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
