AB60E Overhaul Kit 2007-11, new and ready to install. Fits the AB60E. Ships fast from the USA.
If your 2007-2011 Tundra or Sequoia with the 5.7L is leaking at the pan or front seal, takes a long moment to engage Drive on a cold start, or slips because a clutch circuit is bleeding off pressure, the transmission behind it is the Aisin AB60E (AB60F on 4WD trucks). This listing is the gasket and seal overhaul kit for that rebuild: Precision International part K86900EX, new, covering the 2007-11 AB60E and AB60F. It is the soft-parts bag every rebuild starts with, not a plate kit, so you can pair it with exactly the frictions, steels and pistons your teardown shows you need.
The AB60 is Aisin's six-speed rear-drive unit built for Toyota's 5.7L trucks, a heavier relative of the A750 family. It shifts by applying four clutches (C1-C4) and four brakes (B1-B4), each fed by its own hydraulic circuit. Oil travels from the pump through the valve body, through sealing rings on the rotating shafts and drums, and into a piston cavity sealed by lip seals or O-rings. Every one of those rings and seals is a potential leak path. As they harden with heat and age, apply pressure leaks past them, the piston fills slowly or never reaches full force, and the clutch pack slips even if its plates still have life.
The K86900EX bag replaces those sealing parts: the sealing rings, the rubber seals and O-rings, the paper gaskets and the pan gasket. It does not include friction plates, steel plates, bonded pistons, a filter or a torque converter.
Start with a scan. The AB60E is known for solenoid and valve body faults, and a sticking shift solenoid feels a lot like a worn or leaking clutch, so record any codes and check whether the problem follows a specific shift. Then check the fluid level correctly: there is no dipstick, so set the level at the check plug with the engine running and the fluid at the temperature the service information specifies on a scan tool. If the fluid is clean and the level is right, look at the AB60E solenoid kit before pulling the transmission. If the fluid is burnt or full of debris, plan for plates as well as seals. Our Aisin harsh or delayed shift walkthrough covers the order of checks.
The listing covers the AB60E (2WD) and AB60F (4WD) for 2007-2011, which means the 5.7L Tundra from 2007 and the 5.7L Sequoia from 2008. The AB60 family was revised over its run and later units also went into the Land Cruiser and LX570, so confirm the transmission code on the case tag, compare the pan gasket and sealing rings with your old parts at teardown, and send us your year and VIN if you are unsure. More Toyota and Lexus transmission parts are in our Aisin parts collection.
We carry several AB60E kits, and the difference is what comes in the box. This one is the seal and gasket bag only, which suits a rebuilder who is sourcing plates separately or a unit with healthy clutches and leaking seals. The AB60E overhaul kit with frictions and steels adds full plate sets, and the AB60E overhaul kit with pistons, filter and C2 frictions covers the pistons that commonly fail.
This kit is new and ships fast from the USA.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. It is the gasket and seal set: sealing rings, rubber seals and O-rings, paper gaskets and the pan gasket. Frictions, steels, pistons and the filter are separate.
Yes, it is listed for both the AB60E (2WD) and AB60F (4WD) in 2007-2011. Confirm the transmission code on the case tag and send us your year and VIN if you are unsure.
Toyota WS (World Standard) ATF. There is no dipstick, so the level is set at the check plug with the engine running and the fluid at the specified temperature.
Only if the slip comes from a leaking circuit and the plates are still good. If the fluid is burnt or the frictions are worn down, you need plates as well, so inspect them at teardown.
Yes. Reset the transmission adaptive values with a capable scan tool after the rebuild, then drive the truck through all six gears so the computer can relearn shift timing.
