A750F Valve Body 2007, remanufactured and ready to install. Fits the A750F. Ships fast from the USA.
The A750F is the four-wheel-drive version of Toyota and Aisin's five-speed truck automatic, and in 2007 it was behind 4WD Tacoma, 4Runner, FJ Cruiser and Tundra models as well as the Lexus GX470. When one of those trucks starts flaring on the 2-3 shift, slipping in fifth, banging into gear, or shuddering as the converter locks up on the highway, the valve body is a prime suspect. This is a remanufactured A750F valve body for 2007 that replaces the full hydraulic control assembly, solenoids and castings together.
The A750F shifts entirely by computer command. The engine and transmission control module switches the solenoids on the valve body, and the valve body turns those electrical signals into hydraulic pressure aimed at five clutches and brakes plus the converter lockup clutch. One of the more important circuits feeds the B1 brake, which holds in fifth gear and provides engine braking. Sonnax documents that wear in the B1 apply control plunger sleeve lets line pressure escape, producing fifth gear complaints, a burnt B1 brake, low line pressure and slipping in Forward or Reverse. On a truck that tows or climbs grades, that leak is what turns a shift complaint into burnt friction material.
Verify the fluid level at the check plug with the fluid in the correct temperature range, because an underfilled A750F slips and flares like a worn valve body. Inspect the pan for clutch material and metal; heavy debris means internal clutch damage that a valve body will not fix. Then read codes carefully. Toyota names each solenoid differently in the repair manual, parts catalog and scan tool, so a code like P0986 can point to a part with three different names. Cross-reference before you condemn anything, and bench test a suspect solenoid with our solenoid bench testing guide. If the solenoids test good and the truck still flares or slips under load, the Aisin slipping under load guide helps separate worn valve body bores from worn clutches.
This listing is a 2007 A750F valve body. The F suffix marks four-wheel-drive and part-time 4WD applications; two-wheel-drive trucks use the A750E, and the 2007 A750E valve body is the match for those. Engine choice and build date affect the calibration and solenoid layout, and Toyota used two different upper body covers (casting numbers 89010 and 8850) with different checkball layouts on this valve body family. Compare the casting numbers, solenoid count and connectors to the unit you remove, or send your year, model and VIN so we can confirm it first. The 2007 Tundra with the 5.7 V8 uses a six-speed and does not take this part. See the rest of this family in our Aisin transmission collection.
Drain the pan, remove the filter, unplug the solenoid connectors and note where each bolt length goes before you lower the old valve body. Check that the manual valve lines up with the selector detent lever as the new unit goes up. Install a new filter and pan gasket, refill with Toyota WS ATF only, and set the level at the check plug with the fluid at the specified temperature. Clear codes and reset the transmission adaptive values so the computer relearns shift timing; our guide to adaptive relearn after a valve body swap explains what to expect on the first drives. If your codes pointed to individual solenoids rather than hydraulic wear, the A750F solenoid kit is the lower-cost repair, and if the pan showed friction debris the A750E/F overhaul kit is the job to plan for.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
They share the same five-speed design. The A750F is used in four-wheel-drive applications and the A750E in two-wheel-drive. Order the version that matches your drivetrain and casting numbers.
Four-wheel-drive versions of the 2007 Tacoma V6 automatic, 4Runner, FJ Cruiser, Tundra with the V6 or 4.7 V8, and the Lexus GX470. Confirm with your VIN; the 5.7 V8 Tundra uses a six-speed.
It can if the cause is lost B1 apply pressure from valve body wear. If the B1 brake is already burnt, the friction material needs replacing too.
Toyota WS ATF. Set the level at the check plug with the fluid in the specified temperature range; do not top it up with a generic multi-vehicle ATF.
Clear codes and reset the transmission adaptive values, then drive the truck through all gears so the computer relearns shift timing for the new valve body.
