A760E Master Rebuild Kit, new and ready to install. Fits the A760E. Ships fast from the USA.
The A760E six-speed sits behind two very different kinds of vehicle: Lexus sport sedans like the IS350 and GS350, and the 4.6-liter V8 Tundra and Sequoia that spend their lives towing. Either one can end up with the same problem after enough miles and heat: a transmission that slips on the highway, flares between gears, smells burnt, or keeps logging ratio and solenoid codes. When the clutch packs are the cause, the repair is a full overhaul, and this master rebuild kit supplies the frictions, steels, seals and gaskets for the A760E to do it in one pass.
Aisin designed the A760E by adding a sixth gear to the A750 five-speed. First through fifth keep essentially the same ratios, and sixth is a deep overdrive near 0.59 that lets a V8 truck cruise at low engine speed. Getting six forward ratios and reverse out of that gearset means several clutches and brakes are handing off torque on every shift, and the computer times those handoffs with solenoid pressure while it measures input and output speed. Wear is never limited to one pack. By the time one clutch slips badly enough to notice, the rest have been running in the same overheated, contaminated fluid, and the piston seals have hardened with it. Renewing only the failed pack leaves the others to fail next, which is why rebuilders treat a master kit as the minimum for this unit.
Start with the fluid, because these units are leveled at a check plug with the fluid at a specified temperature, and an incorrect level is a common cause of slip on trucks that have had a careless pan service. Then measure line pressure; a worn pressure regulator or solenoid feed problem in the valve body can make healthy clutches slip, and our line pressure testing guide shows the method. Sonnax notes that on these six-speeds a slipping clutch sets the very same performance codes as a sticking solenoid, so a road test comparing commanded gear with actual ratio is the deciding check. Towing trucks deserve a look at cooling too; our Aisin overheating guide explains how heat kills these clutches and how to stop it from happening again after the rebuild.
This listing covers the A760E and references the A761E. Known A760E applications include the rear-wheel-drive Lexus IS350 and GS350 and, from 2010, the rear-drive 4.6-liter Tundra and Sequoia. Four-wheel-drive Tundra, Sequoia and the GX460 use the A760F, and all-wheel-drive Lexus cars use the A760H. The A761E behind the 4.3-liter V8 Lexus models has different gear ratios. Because internal parts changed across production years, read the transmission code from the case, compare it to your vehicle, and send us your year and VIN if there is any doubt. If you have a 2006-2009 car, we also stock a 2006-2009 A760E master kit. Everything else for this family is in our Aisin collection.
Disassemble completely and clean every part before deciding what to reuse. Drums, bushings, the pump, thrust washers and planetary carriers are hard parts the kit does not include, and any that show scoring, bluing or play should be replaced. Soak frictions in Toyota WS ATF, measure each pack clearance against the factory figure, and air-check pistons before the valve body goes on. Since slipping clutches usually travel with worn valve body bores on this family, budget for a valve body shift kit or a remanufactured 2010-2022 valve body. Fill with Toyota WS, set the level hot at the check plug, and clear adaptive memory before road testing.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The rear-wheel-drive 4.6L Tundra and Sequoia use the A760E. Four-wheel-drive versions use the A760F, which shares the gearbox but has a different output section, so confirm with your transmission code or VIN before ordering.
The GX460 uses the A760F four-wheel-drive version. Send us your VIN and we will confirm whether this kit matches your unit.
This listing is not year-specific, while the other is listed for 2006-2009 units. If your transmission falls in that range, compare both and choose the one that matches your build.
Toyota WS ATF only. Set the level at the check plug with the fluid at the specified temperature.
If the old clutches burned, the converter has been circulating that debris and should be replaced or professionally rebuilt and flushed along with the cooler lines.
