A750E Valve Body 2003-2007, remanufactured and ready to install. Fits the A750E. Ships fast from the USA.
Early A750E five-speed automatics in the 2003-2007 Toyota 4Runner, Tacoma and Lexus GX470 are known for harsh or flared shifts and torque converter clutch shudder as the valve body ages, and that is almost always a wear problem inside the valve body rather than a sign the transmission is finished. This remanufactured A750E valve body is built specifically for the 2003-2007 production run and bolts in as a direct replacement for the original.
On the early A750E, the valve body carries the shift solenoids and pressure control solenoid that the transmission control module fires to run the five forward gears, and it routes line pressure through a set of precision bores and spool valves to apply each clutch pack and band on command. Early-production units have had the longest time in service of any A750E valve body on the road, so bore wear and the pressure leakage that comes with it are the most common failure here - the hydraulic hardware wears out well before the gearset usually does.
These early units are also where Toyota's solenoid naming gets confusing fastest - a solenoid labeled SR in the repair manual and SSE on a wiring diagram is the same physical part the parts catalog lists under a numbered 3-way solenoid designation, which matters if you are cross-referencing a fault code against a parts order.
Scan for codes before buying parts. Shift solenoid and pressure control solenoid performance faults, along with TCC performance or stuck-off codes, are what typically point back to a worn valve body on this generation. Road test with live scan data and compare commanded versus actual gear, since a wiring fault can mimic a bad valve body and a scan tool alone will not always tell the two apart.
This valve body is built for the A750E as produced from 2003 through 2007, covering the Toyota 4Runner, Tacoma and the Lexus GX470. Toyota changed internals more than once during this window, so match the casting and connector against your old unit, or send your year and VIN before ordering to confirm you get the correct early-production revision. If your vehicle falls outside 2003-2007, see the A750E valve body for 2005-2009 or the standard A750E valve body.
Change the fluid and filter at the same time as the valve body so wear debris from the old unit is not drawn back through the new one. Toyota WS ATF is the correct spec for this transmission; the wrong fluid will reproduce the same harsh-shift symptoms you are replacing the valve body to fix. Torque the bolts down in the factory sequence rather than snugging them randomly, since uneven clamping can warp the body and reopen the bores you just installed. Run a full relearn cycle after the swap so the control module resets clutch fill timing for the new hardware. Because these early units have the most mileage of any A750E on the road, it is also a good time to check the filter kit and planetary for wear - see the transmission filter and gasket kit and A750E planetary for 2003.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
This listing is built specifically for the A750E as produced from 2003 through 2007 in the 4Runner, Tacoma and Lexus GX470. Because Toyota revised internals more than once during this window, match your casting and connector against the old unit, or send your year, model and VIN so we can confirm fitment before it ships.
Harsh or flared shifts (especially the 2-3), slipping under load or towing, torque converter clutch shudder at cruise, and a delayed upshift are the common complaints. A shift or pressure control solenoid fault code is often stored alongside these symptoms.
Usually, but confirm with a road test and live data first, since a wiring fault can produce similar symptoms. Toyota also uses different names for the same solenoid across the repair manual, parts catalog and scan tool, so match the actual component, not just the code label, before ordering.
Change the fluid and filter so old debris does not circulate through the new valve body. These early units carry the most mileage of any A750E on the road, so it is worth checking the filter kit and planetary for wear while the pan is down.
Toyota WS (World Standard) ATF. Running the wrong fluid spec causes the same harsh-shift and flare symptoms as a worn valve body.
