P2756Torque Converter Clutch Pressure Control Solenoid
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- 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.
- What you may notice
- Converter lockup missing or unstable

- Likely causes
- LikelyInternal transmission damage or debris in the valve body (Toyota 8-speed)
- PossibleLockup pressure solenoid sticking or worn
- RareWiring or connector fault on the solenoid circuit
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
