A750E Clutch Drum, used and ready to install. Fits the A750E. Ships fast from the USA.
If your Toyota 4Runner, Tacoma, Tundra, Sequoia or FJ Cruiser has an A750E that slips in some gears but not others, shows brass or steel glitter in the pan, or came apart on the bench with a scored or cracked drum, this is the hard part you are looking for. It is a used, original-equipment A750E clutch drum pulled from a running unit, so you get factory metallurgy and machining instead of an aftermarket casting. In the product photo the drum is still assembled on its input shaft, which is how most rebuilders want it: the shaft journals and the drum come out of the same transmission and have worn in together.
The A750E is Aisin's 5-speed rear-wheel-drive automatic, and the E in the name means electronic control (the A750F is the four-wheel-drive version of the same gearbox). Toyota's factory service data groups the forward, direct and reverse clutch specifications together under the clutch drum and input shaft assembly. The drum is the housing those clutch packs live in: it carries the steel plates on its splines, holds the apply piston and return springs, and has sealing ring lands that feed apply oil from the pump stator into the piston cavity. Engine torque comes in through the input shaft, so if a drum cracks at the splines or a sealing ring land wears, the clutch it carries loses apply pressure and starts to slip under load.
Keep in mind that the A750 family's best-known complaints are solenoid faults and valve body wear, and both can mimic a bad drum. A worn line pressure boost valve, for example, stops pressure rising under throttle and can burn frictions on an otherwise healthy drum.
Start with a line pressure test and a time lag test before you buy hard parts. Toyota's A750F data calls for 52 to 62 psi in Drive at idle and less than 1.2 seconds for neutral to Drive engagement (less than 1.5 seconds neutral to Reverse). Low pressure in every range points at the pump or valve body; normal pressure with a long lag or slip in one range points toward a clutch pack, its piston or the drum. Our Aisin slipping under load guide walks through separating these, and the ATF color and smell chart helps you read what came out of the pan. Once the unit is apart, inspect the drum splines for cracks, check the sealing ring lands for grooves, and measure the bushings against factory limits.
This drum is listed for the A750E and cross-references to the A750F. The A750E was used in the 2003-2009 V8 4Runner, 2005-on V6 4Runner, 2005-2015 V6 Tacoma, 2005-2009 Tundra, 2004-2009 Sequoia and the 2WD FJ Cruiser, while 4x4 versions of those trucks plus the Lexus GX 470 carry the A750F. The listing does not name a specific model year, and Toyota revised internal parts over this long production run, so compare the drum, shaft length and spline count with your old part before installing, or send us your year and VIN and we will check it. You can browse other parts for this gearbox in our Aisin transmission parts collection.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The listing cross-references the A750F, and the two transmissions share the same gear train; the F version adds the transfer case output. Compare the drum and input shaft against your original, or send us your year and VIN to confirm before ordering.
It is a used original-equipment drum shown on its input shaft. Plan to install new clutches, steels, seals and sealing rings with it rather than reusing the old ones.
Run a line pressure test and a time lag test first. Low pressure in every range usually means pump or valve body; normal pressure with slip or long engagement in one range points to that clutch pack, its piston or the drum. Then inspect the drum for cracked splines, grooved sealing ring lands and worn bushings.
Toyota's A750F service data lists 0.50 to 0.80 mm for the direct and reverse clutches and 0.60 to 0.90 mm for the forward clutch, set with the selective flange thickness.
Use the Toyota ATF listed in your owner's manual, which is Toyota WS on most A750 trucks, and check the level hot through the fill and check plug procedure.
Yes. Clear adaptive values with a scan tool if yours supports it and drive the truck through all gears under light and moderate throttle so the transmission computer re-learns clutch fill times.
