A750E Valve Body 2007, remanufactured and ready to install. Fits the A750E. Ships fast from the USA.
A 2007 Toyota Tacoma, 4Runner, FJ Cruiser or V6 Tundra with the five-speed automatic that now slams into gear, flares when it goes from second to third, hunts between fourth and fifth on the highway, or shudders as the converter locks is a textbook case of a tired valve body. By this model year the A750E had been in production for five seasons, and the trucks built in 2007 are now well into the mileage where bore wear catches up with them. This listing is a remanufactured A750E valve body for 2007, a complete hydraulic control assembly you bolt in as one unit rather than chasing individual valves.
Toyota and Aisin built the A750E as an electronically shifted five-speed for rear-drive and part-time four-wheel-drive trucks. There is no throttle cable and no governor; the engine and transmission computer decides every shift and switches solenoids mounted on the valve body to make it happen. The valve body then does the hydraulic work, sending regulated line pressure through spool valves to the clutches and brakes that make each ratio, including the B1 brake that holds in fifth and supplies engine braking. It also feeds the lockup circuit that applies the torque converter clutch at cruise. When the aluminum bores wear oval around those spool valves, oil leaks past instead of building pressure, and the computer can only command a shift that the hydraulics no longer deliver cleanly.
Do the cheap checks before spending this kind of money. Check the fluid level properly at the overflow check plug with the fluid inside the temperature window the service information gives, because a low fill on this transmission produces the same flare and slip a worn valve body does. Look at the condition of the fluid and what is in the pan; clutch material and metal mean the problem is bigger than the valve body. Then pull codes and road test with live data. Toyota labels the same solenoid differently in its repair manual, parts catalog and scan tool, so cross-reference before you condemn one. If a single solenoid is the culprit, bench test it using our solenoid bench testing guide. If the electrical side is clean and the complaint is a shift that flares or a slip under load, our Aisin harsh and delayed shift walkthrough helps you separate a hydraulic control fault from worn friction material.
This valve body is listed for the 2007 A750E. In that model year the five-speed was used in the Tacoma with the 4.0 V6, the 4Runner, the FJ Cruiser and the redesigned Tundra with the V6 and 4.7 V8, and the four-wheel-drive versions are commonly coded A750F. The 2007 Tundra with the 5.7 V8 uses a six-speed and does not take this part. Valve body calibration and solenoid layout can vary with engine, drive type and build date, so match the casting and connector layout to the unit you are removing, or send us the year and VIN and we will confirm it before it ships. Browse every Aisin-built unit on our Aisin transmission parts page, and if your truck falls outside 2007 the 2006-2018 A750E valve body covers the longer run.
The valve body comes out from under the pan on this transmission, so it can be replaced with the unit in the truck. Drain the fluid, remove the pan and strainer, unplug the solenoid connectors, and note where each bolt came from before you drop the old assembly, since the bolts are different lengths. Install the new unit, torque the bolts to the factory specification in the factory sequence, and fit a new strainer and pan gasket; our A750E filter and pan gasket kit covers both. Refill with Toyota WS fluid only, then set the final level at the overflow plug at operating temperature. Clear codes, reset the transmission learned values with a scan tool that supports it, and drive the truck through every gear so the computer can relearn shift timing; our adaptive relearn guide explains the drive cycle. If the old fluid was dark and the clutches are already slipping, a valve body will not bring them back, and an A750E overhaul kit is the right companion purchase.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. The 2007 Tundra with the 5.7 V8 uses a six-speed automatic. This part is for the A750E five-speed used in 2007 Tacoma, 4Runner, FJ Cruiser and the V6 and 4.7 V8 Tundra. Send us your VIN if you are unsure which transmission you have.
Check the listing photos against your old unit. If your existing solenoids test good and you are reusing them, transfer them carefully and keep each one in its original position, because the shift, line pressure and lockup solenoids are not interchangeable.
Toyota WS (World Standard) ATF. Do not substitute Dexron or a universal fluid; the shift calibration is built around WS viscosity, and the wrong fluid can cause flare and lockup shudder on its own.
Yes. Clear codes and reset the transmission learned values with a capable scan tool, then drive through all five gears with light and moderate throttle so the computer can rebuild its shift adaptation for the new hydraulics.
Usually not. Slipping in every gear with dark, burnt fluid points to worn clutches or a pump problem. A valve body corrects pressure control and shift timing, not friction material that is already gone.
