A750E Valve Body, remanufactured and ready to install. Fits the A750E. Ships fast from the USA.
If your Tacoma, 4Runner, Tundra, FJ Cruiser, Sequoia or Lexus GX470/GX460 is shuttle-shifting, binding or flaring on the 2-3 upshift, slipping in 3rd or 4th gear, kicking down roughly at highway speed, or has stored a shift-solenoid or torque converter clutch (TCC) code, the valve body is the usual point of failure on the A750E. This is a remanufactured, bench-ready valve body, so you install a known-good hydraulic and electronic assembly instead of chasing worn bores and tired solenoids piece by piece.
The A750E is Toyota/Aisin's 5-speed rear-wheel-drive electronic automatic used across the Tacoma, 4Runner, Tundra, FJ Cruiser and Sequoia, and the Lexus GX470/GX460 under the A750F designation. The valve body is the hydraulic brain of the unit - it routes line pressure through precision bores and spool valves to apply each clutch, and because this is an electronically controlled transmission, it also carries the shift and pressure-control solenoids the computer uses to time every shift and to manage TCC apply and release.
TransGo's own technical notes for this transmission family identify a worn TCC relay valve bore as the first area of concern behind TCC-related complaints - once that bore wears, the computer loses the ability to control lock-up apply slippage and release rate. A worn solenoid modulator valve bore is the second common cause, since it stops regulating feed pressure to the solenoids correctly, which shows up as shift-quality complaints alongside the solenoid and ratio codes above. Confirm which shifts and codes you are actually seeing before ordering, since a solenoid-only fault can sometimes be fixed without replacing the whole valve body.
This valve body is built for the A750E. Toyota and Aisin carried this transmission across a long production run with internal updates along the way - our A750F listing for 2003-2005 covers the earliest version separately - so match your casting marks and connector count against the listing photos, or send us your year and VIN so we can confirm the exact revision before you buy. The full Aisin transmission parts collection has the rest of what we stock for this transmission, including the A760E used in later Tacoma and Tundra applications.
Drop the pan and change the filter at the same time as the valve body swap so debris from the old unit does not circulate into the new one, and refill with genuine Toyota WS ATF - the same WS fluid spec used across this Toyota/Aisin electronic-transmission family. Torque the valve body bolts in sequence to spec rather than corner to corner, clear codes, and run the computer's adaptive relearn after the swap so shift timing and TCC apply are retaught against the new unit instead of the worn one. If your complaint included 5th-gear slip, reverse slip or a burned B1 clutch rather than just a TCC or shift-quality code, inspect the B1 clutch pack before reinstalling, since a worn clutch will wear a new valve body the same way. For a full rebuild instead of a valve body swap, see our A750E/A750F master rebuild kit, and replace the pressure control solenoid or TCC solenoid separately if your scan tool points to just one circuit.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It replaces the worn hydraulic bores and electronic solenoids that cause shuttle shifts, 2-3 flare, slipping in 3rd/4th, rough kickdown and stored shift-solenoid or TCC codes - it does not fix a worn clutch pack or burned B1 clutch on its own.
P0746, P0751, P0756, P0771, P0776, P0894, P2714 and P2757 are the shift-solenoid, TCC performance and ratio codes commonly tied to valve body bore wear on this family.
A worn TCC relay valve bore is the most common cause - it stops the computer from controlling lock-up apply slippage and release rate. A worn solenoid modulator valve bore, which stops regulating feed pressure correctly, is the second common cause.
It's built for the A750E/A750F family, but Toyota and Aisin ran internal updates across this transmission's long production run, so match casting marks and connector count against the photos or send your VIN to confirm before ordering.
Genuine Toyota WS ATF, the same fluid specification used across this Toyota/Aisin electronic-transmission family.
Check the B1 clutch pack first. 5th slip, reverse slip and burned B1 clutches are usually a clutch wear issue, not a valve body issue, and installing a new valve body onto a worn clutch pack will wear it the same way.
