AB60E Overhaul Kit, new and ready to install. Fits the AB60E. Ships fast from the USA.
When a Toyota Tundra, Sequoia, Land Cruiser or Lexus LX570 with the 6-speed AB60E has started to slip on the 2-3 or 3-4, flares when hot, or takes a long time to engage after sitting, a seal or piston somewhere in the unit is usually leaking apply pressure. This AB60E overhaul kit is the sealing side of a rebuild: the full gasket and seal set, a bonded piston kit and an internal filter, for 2007-on units. Pair it with frictions and steels and you have what it takes to bring a high-mileage AB60E back to factory clamping pressure.
It does not include friction plates, steel plates, bushings or hard parts. Most rebuilders add a friction pack such as the one in our AB60E banner rebuild kit, or step up to a complete AB60E/AB60F master rebuild kit if you want everything in one box.
The AB60E (Aisin TB-68LS) is a big rear-drive 6-speed built for the 5.7L Tundra and Sequoia starting in 2007. It shifts with four clutches (C1-C4), four brakes (B1-B4) and four one-way clutches, all applied by hydraulic pistons the valve body feeds through sealing rings on the shafts and drums. Every one of those circuits has to hold pressure. When a piston lip hardens, a bonded seal starts to peel, or a sealing ring wears its groove, oil bleeds off during the apply and the pack slips instead of locking. That is why sealing rings and pistons are replaced as a set on any AB60E teardown, and why reusing original pistons is the most common reason a fresh rebuild comes back.
Scan for codes first. A shift solenoid, line pressure or valve body fault can feel exactly like a worn seal, and the fix is very different. Check the fluid level the Toyota way, at temperature with the engine running, since an AB60E with no dipstick is often simply low. If the fluid is dark and smells burnt with friction material in the pan, the unit needs to come out and this kit is part of the job. Our Aisin slipping under load guide walks through separating a pressure problem from a worn clutch pack, and harsh or delayed shifts covers engagement complaints.
The kit is listed for the Toyota AB60E, 2007-on. The AB60E (2WD) and AB60F (4WD) share the same seal and piston set in the main case; the AB60 is used in the 2007-2021 Tundra 5.7L, 2008-2022 Sequoia 5.7L, 2008-2022 Land Cruiser and 2008-2015 Lexus LX570. Internal filters changed around 2015, so compare the filter in this kit with the one in your pan before installing it. If you are unsure, send us your year and VIN. More parts for this and other Aisin units are in our Aisin transmission parts collection.
Soak bonded pistons and lip seals in Toyota WS fluid before assembly, and lube sealing rings with assembly gel so they stay centered when the drums go on. Inspect every sealing ring groove and drum bore for wear steps; a new ring in a worn groove will still leak. Air check each clutch and brake circuit before closing the case. Since the valve body is out anyway, inspect it or replace it with our AB60E valve body if it has a history of solenoid codes. Refill with Toyota WS only, set the level at the correct temperature, then reset the transmission adaptive values with a scan tool so the ECU relearns the new clutch fill times.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. It is the gasket and seal set with a bonded piston kit and a filter. Frictions and steels are sold separately or in a master rebuild kit.
The AB60E and AB60F use the same main-case seals and pistons. 4WD units have a transfer adapter, so check the rear seal with your teardown and send us your VIN if you want us to confirm.
Toyota WS (World Standard) ATF. Do not substitute a universal Dexron or Mercon fluid.
Bonded piston lips harden and shrink with heat and age. A piston that looks fine can still leak apply pressure, which causes slipping right after the rebuild.
Yes. Reset the adaptive values with a scan tool so the ECU relearns clutch fill on the new seals and frictions, then drive it gently through all gears.
