A750F Overhaul Kit 2002, new and ready to install. Fits the A750F. Ships fast from the USA.
A four-wheel-drive Toyota or Lexus with the five-speed A750F that drips fluid at the transfer case adapter, takes a second to grab Drive on a cold morning, or is simply on the bench for a teardown needs a complete set of gaskets and seals before it goes back together. This A750F overhaul kit is that set. It is catalogued from 2002, which is how kit makers label the early A750 family; in the United States the transmission itself first appeared in 2003 trucks such as the four-wheel-drive 4Runner and the Lexus GX470.
The A750F is the four-wheel-drive version of the Aisin five-speed rear-drive automatic. Its gear train and valve body match the two-wheel-drive A750E, but the back of the case is built to bolt to a transfer case, so it carries its own adapter gasket and output seal that a 2WD unit does not use. Every gear is applied by a hydraulic piston clamping a clutch or brake pack, and the pressure that does the clamping must travel from the pump, through the valve body and across sealing rings on spinning shafts. An overhaul kit renews the parts that hold that pressure in: the pan and case gaskets, piston lip seals, sealing rings and O-rings. It does not include friction plates or steels. The product photo shows the gasket sheet packed together with the rubber seals and sealing rings in one bag, so you are not hunting for the last O-ring halfway through assembly.
Look at the fluid and the pan first. Red fluid, a clean magnet and a cold-start delay fit hardened seals, and this kit alone is the repair. Dark, burnt fluid with friction material in the pan means the clutch packs are finished too, and you will want frictions and steels such as those in the A750F master rebuild kit. TransGo notes that worn line pressure boost valves on 2003-and-later A750 units keep line pressure from rising under load, which can mimic a seal leak, so a line pressure test is worth doing before teardown. A leaking front seal often traces back to a worn converter hub or pump bushing; our guide to converter hub and pump bushing wear shows how to check it.
The listing is for the A750F, catalogued 2002. Real-world applications start with the 2003 4Runner, GX470, LX470 and Land Cruiser and continue into the Tacoma, Tundra, Sequoia and FJ Cruiser four-wheel-drive trucks from the mid-2000s. Toyota made running changes over those years, so lay the new gaskets over your originals before you commit to assembly, and send us your year and VIN if you want fit checked first. If you have a two-wheel-drive truck you need an A750E kit instead; see the other A750 parts on our Aisin transmission page.
After the rebuild, clear learned shift values so the computer adapts to the fresh seals rather than to the old leaks.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Kit catalogs often start the A750 range at 2002. In the United States the A750F went into 2003 model year vehicles, so a 2003 or later A750F truck is the intended application. Compare gaskets against your originals during teardown to confirm.
No. An overhaul kit is the gasket and seal set. If your fluid is burnt or the pan shows friction material, you also need frictions and steels, which come in a master rebuild kit.
The internal seals are shared, but the A750F has a transfer case adapter where the A750E has a tailhousing, so the rear gasket and seal differ. Order the A750E kit for a 2WD truck.
Sometimes. The adapter gasket and output seal can be replaced with the transmission in the truck if the leak is only external. The full kit makes sense when the transmission is already coming apart.
Toyota WS automatic transmission fluid. Set the level using the overflow or check plug procedure at the specified fluid temperature for your vehicle rather than guessing.
