A760E Shift Kit, new and ready to install. Fits the A760E. Ships fast from the USA.
If your Tundra, Sequoia, Lexus IS or GS with the A760E six-speed is flaring on the 2-3 shift, slipping in 3rd or 4th under throttle, or setting lockup and solenoid performance codes, the valve body bores are a likely cause. This is the new TransGo SK A750-WTA SHIFT KIT valve body repair kit, the version that includes the reusable tools needed to oversize a worn TCC relay valve bore. TransGo lists it for 2003-on A750E/F five-speeds and A760E/H, A761E/H, A960E and AB60E/F six-speeds.
Despite the name, this kit is less about firm shifts and more about restoring hydraulic control the computer has lost. TransGo points to two wear areas. A worn TCC relay valve bore lets the converter clutch apply and release unpredictably, which causes lockup codes and a rough kickdown at highway speed when the clutch releases too slowly. A worn solenoid modulator valve bore lets solenoid feed pressure drift too high or too low, so every shift solenoid outputs the wrong pressure and you get shuttle shifts, 2-3 bind-up or flare, and gear ratio codes. The kit replaces both valves with hardened steel parts in new bushings and adds a TCC control boost valve and bushing.
Codes like P0751 or P2714 can also come from a bad solenoid or harness, so test first. Read live data and commanded versus actual gear with a capable scan tool (our live data guide explains what to watch), check the solenoids with a meter, and confirm fluid level and condition. If the electrical side checks out and the problem is worse when hot, valve body bore wear is the prime suspect. Lockup complaints in particular are covered in our converter clutch shudder guide. Solenoid naming on this family is confusing, because Toyota's manual, parts book and scan data do not always agree, so match circuits by connector and function rather than by letter.
The A760E six-speed went into the 2010-2019 Tundra and Sequoia 4.6L, the 2005-2013 Lexus IS and 2006-2013 GS 350, and other rear-drive Toyota and Lexus models; the A760F and A750E/F share this kit. The same TransGo kit is also listed on our A750E shift kit and A750F shift kit pages. Valve bodies changed during production, so measure your TCC boost valve bushing and use the matching size from the kit. Send us your year and VIN if you want fitment checked, and browse the rest of the family in the Aisin transmission collection.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
TransGo lists SK A750-WTA for 2003-on A750E/F five-speeds and A760E/H, A761E/H, A960E and AB60E/F six-speeds. Valve body revisions vary, so match the TCC boost bushing size to your original.
No extra purchase is needed. This WTA version includes the reamer, guides and drill bits to oversize the TCC relay valve bore. If you already own them, TransGo's refill kit A750-NTA is the parts-only version.
Only if the code comes from valve body bore wear. Test solenoid resistance, the harness and fluid level first. If those are good and the code appears when the fluid is hot, worn solenoid modulator or TCC relay bores are a common cause this kit corrects.
The valve body comes out from under the pan, so the kit can be installed in the vehicle by an experienced technician. Reaming must be done carefully and the valve body cleaned of all chips before reinstalling.
Toyota WS ATF, with level set at operating temperature through the check plug. Clear adaptive learning with a capable scan tool before the road test.
