A760E Master Rebuild Kit 2006-2009, new and ready to install. Fits the A760E. Ships fast from the USA.
If you own a 2006-2009 Lexus IS350, GS300 or GS350 with the rear-wheel-drive six-speed automatic and it now slips when you get on the throttle, flares between the middle gears, or keeps setting solenoid performance codes that new solenoids did not cure, the clutch packs are probably worn out. This master rebuild kit is built for the A760E as it was produced from 2006 through 2009, so a builder can renew every wear part in that unit in one teardown instead of chasing one failed clutch at a time.
The A760E is the six-speed member of the Aisin A750 family, built for longitudinal rear-drive Toyota and Lexus vehicles. It adds a sixth, overdrive ratio of about 0.586 on top of the familiar five-speed gearset, and every one of those ratios is held by a clutch or brake pack that the electronic controls apply and release with linear and on/off solenoids. There is no throttle cable or governor: the computer watches input and output speed and judges each shift by how quickly the ratio changes. When the frictions glaze or the piston seals start to leak, the computer sees slip it cannot correct, and shift quality falls apart. A master kit puts new frictions, steels, seals, sealing rings and gaskets in every circuit at once, which is the only way to restore consistent clutch apply in a unit with this many packs.
Those P07xx performance codes do not mean a solenoid is dead. The computer sets them whenever it commands a gear and sees the wrong ratio from the speed sensors, and a slipping clutch causes exactly that. Road test with a scan tool that shows commanded gear against actual ratio; our guide to reading transmission live data covers what to watch. Then check fluid level properly. These Lexus applications are leveled at the check plug at a specified fluid temperature, not with a dipstick, and a low unit will slip just like a worn one. If the level is right, the solenoids test good and it still slips under load, our Aisin slipping-under-load guide walks through what is left before you commit to teardown.
This kit is listed for the A760E from 2006 to 2009. In North America that range takes in the rear-wheel-drive IS350 and the rear-drive GS300 and GS350. The listing also references the A761E, the V8 version used behind the 4.3-liter Lexus models, but that unit runs different gear ratios, so do not assume the clutch stack-ups match. All-wheel-drive models use the A760H, and the 2006-up IS250 rear-drive car uses a different Aisin six-speed. Match the transmission code on the case tag, or send us your year and VIN and we will confirm before it ships. You can see every A760E part we carry in our Aisin transmission parts collection.
Before anything goes back in, inspect the drums, bushings, pump gears and planetary thrust surfaces; a kit cannot fix a scored drum or a worn bushing. Soak the new frictions in Toyota WS fluid, set each clutch pack clearance to the factory specification, and air-check every circuit before the valve body goes on. A high-mileage A760E that slipped long enough to burn its clutches has usually worn the valve body bores as well, so look hard at the TCC relay and solenoid modulator valves while the unit is apart. Pair the rebuild with a replacement solenoid kit or a remanufactured A760E valve body if those components tested marginal. Fill with Toyota WS only, set the level hot at the check plug, then clear adaptive values and drive the vehicle through a full relearn; our adaptive relearn guide explains why the first drives can feel firm.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
In North America the A760E in those years went into the rear-wheel-drive Lexus IS350, GS300 and GS350. AWD versions use the A760H and the IS250 uses a different six-speed, so check the transmission code on your case tag or send your VIN before ordering.
The listing references the A761E, but the A761E has different gear ratios than the A760E. Confirm against your unit before relying on it, and send us the transmission code if you are unsure.
Toyota WS (World Standard) ATF. Use it to soak the frictions during assembly and for the final fill, and set the level at the check plug with the fluid at the temperature your service information specifies.
Either is possible. Solenoid performance codes set whenever the computer sees the wrong gear ratio, which a slipping clutch also causes. Verify commanded gear against actual ratio on a road test and test the solenoids before deciding.
Any drum, bushing or pump part that fails inspection, plus the filter. If shifts were harsh or the lockup was erratic, the solenoids or the valve body often need attention too.
Yes. Clear the stored adaptive values and drive through repeated light and moderate throttle shifts so the computer can learn the new clutch fill times.
