Frictions, steels, seals and gaskets to rebuild the AB60E six-speed behind the 5.7L V8 in 2007-2011 Tundra and 2008-2011 Sequoia.
If your 2007-2011 Tundra 5.7L or 2008-2011 Sequoia 5.7L has started slipping on the 2-3 shift under a load, takes too long to grab Drive on a cold morning, or smells burnt on the dipstick, the clutch packs in its six-speed AB60E are the usual cause. This is a budget master rebuild kit for that transmission: a full set of friction plates and steel plates together with the valve body gaskets, the pan gasket and the seal and O-ring set, so a bench rebuild can renew every clutch pack and reseal the case from one box.
The AB60E (Aisin TB-68LS) is the rear-drive version and the AB60F the four-wheel-drive version of the same gearbox, and both use the same clutch packs inside. Transmission Digest traces the design back to the A750E five-speed, stretched into a six-speed through the A761E with an extra clutch pack and sprag. That leaves eight separate friction elements, four clutches and four brakes, each applied by a piston that relies on a good seal. When a hot transmission glazes the lining and hardens those seals, apply pressure bleeds off and the TCM sees slip. A master set replaces both halves of the problem: new frictions and steels give each pack a fresh, flat surface, and the gaskets and seals hold the pressure that clamps them. The four separator plate gaskets in the photo are what keep the valve body circuits sealed after it has been removed.
Heat is what kills these units, and a failed cooler thermostat or a worn torque converter can cause symptoms that look like clutch slip. Read our Aisin overheating guide before condemning the clutches, then use the slipping under load guide to compare engine speed with output speed during a loaded upshift. If you are still weighing a rebuild against a swap, our rebuild, replace or reman comparison lays out the costs.
This kit is listed for the Toyota Tundra 5.7L V8 2007-2011 and the Toyota Sequoia 5.7L V8 2008-2011, in AB60E and AB60F form. The AB60 family stayed in production well past 2011 and also went into Land Cruiser and Lexus LX570 models, but this listing only names the 2007-2011 trucks, so read the tag on your transmission and match it before ordering. When in doubt, send us your year and VIN. More parts for this transmission are under Aisin transmission parts.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is listed for the 2007-2011 Toyota Tundra 5.7L V8 and the 2008-2011 Toyota Sequoia 5.7L V8, in both AB60E (two-wheel drive) and AB60F (four-wheel drive) form. Check your transmission tag, or send your year and VIN.
No. It contains friction plates, steel plates, valve body gaskets, the pan gasket and the seal set. Buy the filter separately and replace it on every rebuild.
Only after it has been cleaned or rebuilt. A converter that has been running in burnt fluid holds clutch debris that will contaminate the new frictions.
Toyota WS ATF. Set the level at operating temperature through the check plug. The wrong fluid can cause lockup shudder on these units.
Inspect the forward drum, the bushings and the pump, which this kit does not include. Replace the filter, flush the cooler, and check the cooler thermostat.
