AB60E Clutch Drum 2007, used and ready to install. Fits the AB60E. Ships fast from the USA.
A 2007-up Toyota Tundra, Sequoia, Land Cruiser or Lexus LX 570 that pulls fine through third, then flares, slips or refuses to take fourth, fifth and sixth is pointing at the C2 direct clutch, and a cracked or worn C2 housing will burn a fresh friction pack in short order. This listing is a used Toyota direct clutch drum for the AB60E and AB60F: the steel, 5-clutch housing, 4.692 in. tall, sold under interchange number 77555A. It replaces the drum itself so you are not reusing a damaged housing behind new plates.
The AB60E is Aisin's TB-68LS six-speed, the heavy-duty big brother of the A750/A761 family, built for the 5.7L Tundra and Sequoia. It uses four clutches and four brakes. Raybestos lists the C2 position as the 4-5-6 direct clutch with five waved frictions, which matches this 5-clutch drum. The drum holds that friction and steel stack, carries the C2 apply piston, and takes its apply oil through sealing rings on its hub. When the piston strokes, the pack locks the drum to its mating hub and the transmission can make fourth, fifth and sixth. Every upper gear on a highway truck runs through this one housing, which is why a weak C2 shows up the moment the truck is loaded or towing.
On these trucks solenoid faults and clutch faults set the same performance codes. GEARS Magazine documented a 2007 Tundra with an AB60F that came in with P2714 and P0766, no fifth or sixth, and burnt fluid; teardown found a burnt C-2 clutch. Sonnax makes the same point in its solenoid-performance article: a slipping clutch can set the code that points at a solenoid. Before buying hard parts, check the fluid level at the fill plug, scan for codes, and read line pressure; GEARS published 50-60 psi at idle and 180-195 psi at stall in Drive for that truck. Our guide to Aisin slipping under load walks through separating a pressure problem from a worn clutch. With the case open, air-check the C2 piston, inspect the drum for cracks around the spline teeth and the piston bore, and look at the hub where the sealing rings ride. Grooved ring lands or a cracked housing mean the drum gets replaced, not just the plates.
This drum is listed for the AB60E and AB60F, 2007 and up, which covers the Toyota Tundra, Sequoia and Land Cruiser and the Lexus LX 570. The E is the two-wheel-drive version and the F is the four-wheel-drive version; the direct drum is shared. Because this is a used part, match it to your original before installing: it should be the steel 5-clutch housing at 4.692 in. tall. If you are unsure, send us your year and VIN and we will confirm it. You can see every AB60 part we stock on the Aisin transmission parts page.
If heat is what cooked the original pack, read Aisin overheating prevention before the truck goes back to towing.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes. It is listed for both, 2007 and up. The F is the 4WD version of the same transmission and uses the same C2 direct drum. Match the 5-clutch steel housing and 4.692 in. height to your original.
The C2 direct clutch, which Raybestos lists as the 4-5-6 clutch with five frictions. If the truck loses fourth, fifth or sixth, this is the pack to inspect.
New C2 frictions and steels, the piston seals and the hub sealing rings at minimum. Most builders do the job with a full overhaul kit since the case is already open.
It can be either. A slipping clutch can set the same solenoid performance code, as GEARS showed on a 2007 Tundra with a burnt C-2. Check fluid condition and line pressure before replacing parts.
Toyota WS ATF. The AB60 has no traditional dipstick; the level is checked at the fill plug at the temperature Toyota specifies.
Clear the adaptive values with a scan tool after the rebuild and drive the truck through all gears so the TCM can relearn shift timing.
