A760E Input Drum 2003, used and ready to install. Fits the A760E. Ships fast from the USA.
Owners of a 2010-2019 Tundra or Sequoia with the 4.6L V8, or a Lexus GS or IS with the A760E six-speed, usually land here after the transmission starts losing Reverse, slipping into fifth and sixth, or showing up on a rebuild bench with a damaged drum. This listing is sold as an A760E input drum, and the part is the Toyota/Aisin direct clutch drum 117555AB: the 4-3/4 inch tall, 7-1/2 inch outside diameter design cataloged for 2003-up A760 units. It is a used original-equipment drum in checked, good used condition.
Compared with the five-speed A750, the A760E keeps the same first five ratios and adds an overdrive sixth of 0.586, so its upper gears lean heavily on the clutches this drum carries. The direct clutch inside the drum is applied in the higher ratios, and the reverse clutch piston rides in the outer bore of the same housing. Each piston receives oil through sealing rings on the drum hub. On a heavy truck such as the 4.6L Tundra, towing heat and torque work on those ring lands and the spline teeth, and once either wears or cracks, the clutch cannot hold full torque.
Because the A760E also suffers shift solenoid, lockup solenoid and valve body problems, confirm the hydraulic side is healthy before you replace hard parts. A solenoid sticking can mimic a slipping clutch almost perfectly.
Scan for transmission codes and watch commanded gear versus actual gear and slip on a road test. Then install a pressure gauge. As a reference, Toyota's A750F data, the five-speed sibling that uses this same drum, lists 52 to 62 psi in Drive at idle and a stall speed of 2,250 to 2,550 rpm; use your own A760E manual for its exact figures. Normal pressure with slip in the upper gears and Reverse puts the direct drum and its seals at the top of the list. Our Aisin slipping under load guide and ATF color and smell chart help narrow it down.
Part 117555AB is cataloged for 2003-up A760E, A760F and A760H units, as well as the A750 and A761 families. A760E vehicles include the 2010-2019 Tundra and Sequoia 4.6L in two-wheel drive, the Lexus GS 300 and GS 350 and the rear-drive IS 350. The A760F covers 4WD Tundra, Sequoia and the GX 460, and the A760H covers all-wheel-drive Lexus models. This is the 4-3/4 inch tall drum; a shorter 4.285 inch version also exists, so measure height and OD or send us your year and VIN. See the full range in our Aisin transmission parts collection.

The two-wheel-drive 4.6L Tundra uses the A760E, and 117555AB is cataloged for 2003-up A760 units. Measure your old drum height and OD or send us your VIN to confirm.
No. That listing is part 117555A, the shorter 4.285 inch drum. This is 117555AB, the taller 4-3/4 inch, 7-1/2 inch OD version. Match the one that came out of your transmission.
Only if the drum or its seals are the cause. Check line pressure and solenoid operation first, then rebuild the direct and reverse packs with new soft parts along with the drum.
117555AB is cataloged for the A760E, A760F and A760H. Confirm your unit's drum dimensions before ordering.
Yes. After filling with Toyota WS ATF and setting the level hot, drive through every gear so the transmission control module can relearn its shift timing.
