A750E Overhaul Kit, new other (see details) and ready to install. Fits the A750E. Ships fast from the USA.
Owners of a Toyota Tacoma, 4Runner, FJ Cruiser, Tundra, Sequoia or Lexus GX470 with the five-speed automatic usually start shopping for an overhaul kit after one of three things: a slip or flare on the 2-3 shift when towing, fluid that smells burnt, or a leak that will not stop. This listing is an overhaul and master rebuild kit for the Aisin A750E (two-wheel drive) and A750F (four-wheel drive). It is sold as new other, meaning new parts that may be in opened or plain packaging.
The A750E is a rear-drive five-speed with ratios of 3.52, 2.042, 1.40, 1.00 and 0.716, plus a lockup converter. The A750F is the same transmission with a transfer case bolted behind it, which is why one kit serves both. Each gear is held by a clutch or brake pack squeezed by a hydraulic piston, and every circuit between the pump, valve body and pistons is sealed by rubber seals, metal clad seals and sealing rings. On a high-mile truck those seals harden and leak pressure, which shows up as soft apply, slow engagement and slip under load. A rebuild kit renews those seals and gaskets in one job so the unit leaves the bench sealed like new instead of a mix of fresh and tired parts.
TransGo documents that 2003-and-later A750 valve bodies wear the TCC relay valve bore, the solenoid modulator valve bore and the line pressure boost valve, and that this wear alone can cause the 2-3 flare, third and fourth gear slip and codes such as P0746, P0751 and P0756. A truck with those complaints but clean fluid may need valve body work rather than a full teardown. Read shift flare versus slip to sort out which you have, and test the lockup circuit; a failed A750E TCC solenoid is a far smaller job than a rebuild. If the pan shows burnt friction material, the clutches are done and an overhaul is the honest fix.
This kit is listed for the A750E and A750F. Those units went into the 2003-2009 4Runner V8, the 2005-and-later 4Runner and Tacoma V6, the 2005-2009 Tundra, the 2004-2009 Sequoia, the FJ Cruiser, and the 2003-2009 GX470 and 2003-2007 LX470. The listing does not break down the kit contents or a year range, so check the product photos against your needs and send us your year and VIN before ordering if you need a specific part included. If you want a kit with every component spelled out, the A750E master rebuild kit for the 4Runner lists its frictions, steels, seals and rings. All A750 parts are grouped on our Aisin transmission page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes. The listing names both. The A750F is the four-wheel-drive version with a transfer case attached, and the transmission internals that this kit services are shared.
The listing describes it as an overhaul and master rebuild kit but does not itemize the contents. Review the product photos, and contact us with your VIN before ordering if you need frictions, steels or a filter confirmed.
The parts are new and unused, but the packaging may be opened or unmarked rather than retail boxed.
Toyota WS automatic transmission fluid. The level is set at the overflow check plug with the fluid at the specified temperature.
It can. Worn boost, TCC relay and solenoid modulator valve bores in the A750 valve body cause flare, slip and TCC codes. Check line pressure and fluid condition before committing to a full overhaul.
