A750E Tcc Solenoid, remanufactured and ready to install. Fits the A750E. Ships fast from the USA.
Highway RPM creeping higher than it used to, a buzz or shudder through the floor at light throttle around 35 to 50 mph, or a check engine light with P2757 on a Tacoma, 4Runner, FJ Cruiser, Tundra or Sequoia with the five-speed automatic all point toward torque converter lockup. This is a remanufactured torque converter clutch solenoid for the Toyota A750E, with the four-wheel-drive A750F as a reference. Toyota's repair manual calls it shift solenoid valve SLU. It lets you repair a lockup fault without buying a full set of solenoids.
The A750E locks its torque converter clutch so the engine and transmission turn together at cruise, which cuts heat and saves fuel. The engine computer decides when to lock up based on throttle, load, speed, temperature and gear. When conditions are right it energizes the SLU, and the SLU sends oil pressure to the lock-up relay valve, which applies the converter clutch. The computer then compares engine speed with turbine (input) speed to check whether lockup really happened. According to the factory manual, if engine speed is still 70 rpm or more above turbine speed during a lockup request, or the two are within 35 rpm when lockup should be off, the computer treats it as an SLU or lockup system fault.
Lockup complaints have more than one cause. Toyota's trouble areas for P2757 list the SLU solenoid, a blocked valve body, the torque converter clutch, internal clutch or gear problems, and low line pressure. Transmission Digest covered a 2005 Tundra A750F where P2757 kept returning after a replacement transmission, a new converter, another valve body and a new SLU solenoid. The common thread was the factory WS fluid: once degraded, it can bring on shudder during flex lockup between about 32 and 42 mph. So check the fluid condition and service history first. Our TCC shudder diagnosis guide and stall test and lockup diagnosis walk through separating a solenoid fault from a converter or fluid problem. Then measure the SLU circuit at the case connector before you pull the pan.
This solenoid fits the Toyota A750E, with the A750F listed as a reference. The A750 family runs behind the 4.0L V6 and 4.7L V8 in Tacoma, 4Runner, FJ Cruiser, Tundra and Sequoia trucks and the Lexus GX470. Several A750E linear solenoids share a similar body, so compare this part with the one you are removing for connector, snout and body shape before you install it. If your truck is a 2003-2009 model, also look at our 2003-09 A750E TCC solenoid and match whichever one is identical to yours, or send your year and VIN and we will check it. The rest of the A750 range is in our Aisin transmission collection.
If several solenoids test weak, the A750E seven-piece solenoid kit replaces them all in one pan drop.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes. Toyota's repair manual calls the torque converter clutch solenoid in the A750E shift solenoid valve SLU, and P2757 is its performance code. Scan tools and parts catalogs may use other names for the same part.
Only if the solenoid is the cause. Degraded WS fluid, a worn converter clutch or a worn lock-up control valve bore can cause the same shudder. Check fluid condition and history first, and change the fluid with the solenoid.
The listing fits the A750E and gives the A750F as a reference. Compare it with your old solenoid or send us your VIN to confirm.
No. The solenoid is serviced from under the truck with the pan and filter removed.
Toyota WS ATF. Set the level at operating temperature using the overflow-plug check procedure.
