AB60E Overhaul Kit 2007, new and ready to install. Fits the AB60E. Ships fast from the USA.
A 2007-and-later Tundra or Sequoia 5.7L that slips in the upper gears when it tows, flares between 4th, 5th and 6th, or leaks at the pan and pump seal is often ready for a full reseal. This AB60E overhaul kit for 2007-up units is a rebuild package rather than a plain gasket set: it combines a complete overhaul (gasket and seal) kit, a three-piston kit, a new filter and five friction discs for the direct clutch. It is new and suits both the AB60E (two-wheel drive) and AB60F (four-wheel drive) versions of the six-speed.
Aisin calls the AB60E the TB-68LS. Transmission Digest describes it as an upsized A761E built in 2007 for the 5.7L trucks: a larger gerotor pump and converter hub, four rotating clutches (C1-C4), four brakes (B1-B4) and four one-way clutches (F1-F4). Every one of those clutch and brake packs is applied by a rubber-sealed piston, and every rotating drum is fed through sealing rings. When those seals harden or the rings wear their grooves, apply pressure leaks off, the packs slip, and the friction material that comes off ends up in the filter and the valve body.
The overhaul kit renews the gaskets, piston seals, O-rings and sealing rings. The three pistons replace pistons that are commonly found damaged or debonded at teardown. The five frictions are identified in the listing as C2 direct clutch discs for the 4th-5th-6th range: 0.059 in. (1.50 mm) thick, 36 teeth, 7.071 in. outside diameter. The C2 drum sits right behind the pump, nested inside the C3 housing, and its plates take a beating in a truck that tows in the upper gears. The direct drum itself is not included. The overhaul kit in the photo is a Toledo Trans-Kit set, but it may ship as either Toledo or Precision International depending on stock.
Many AB60 shift complaints start in the valve body, not the clutches. Scan for codes, confirm fluid level with the engine running and the fluid at the temperature Toyota specifies (the AB60 has no dipstick, so this is done at the check plug with a scan tool reading temperature), and look at the fluid. Clean fluid with one harsh shift usually means a solenoid or the AB60E valve body with solenoids. Burnt fluid with clutch debris means the packs and seals are done. Our guide to Aisin slipping under load walks through the order of checks.
The kit is listed for 2007-up AB60E and AB60F transmissions. Typical applications are the 2007-2021 Tundra 5.7L, the 2008-2022 Sequoia 5.7L, and the AB60F behind the 5.7L in the Land Cruiser and Lexus LX570. Year and model alone do not prove compatibility, because Toyota used different transmissions by engine, drivetrain, production date and market. Read the transmission code on the case tag or the VIN label before ordering, compare the frictions against your old C2 plates, and send us your year and VIN if you are unsure. Every Aisin part we carry is on the Aisin transmission parts page.
If the other packs are worn, the AB60E master rebuild kit for 2007 supplies full friction and steel stacks, and the AB60E shift kit can firm up the shifts for towing.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes. It is listed for 2007-up AB60E (2WD) and AB60F (4WD) transmissions. Confirm the code on your transmission tag, since Toyota used other transmissions in some engines and markets.
A three-piston kit, a transmission filter and five C2 direct clutch friction discs (0.059 in. thick, 36 teeth, 7.071 in. OD). The direct drum is not included.
Possibly. Only the C2 direct frictions are included. Measure and inspect the other clutch and brake packs; if they are burnt or below spec, add a master rebuild kit.
Toyota WS (World Standard) ATF. Set the level at the check plug with the engine running and the fluid at Toyota's specified temperature, read on a scan tool.
Yes. Clear the transmission adaptive values with a capable scan tool, then drive through all six gears several times so the computer relearns shift timing.
