A760E Shift Kit 2003, new and ready to install. Fits the A760E. Ships fast from the USA.
The A760E is the six-speed member of the Aisin A750 family, and it shows up in two very different kinds of vehicle: rear-drive Lexus sedans such as the IS250, IS350, GS300 and GS350, and the 4.6-liter V8 Tundra and Sequoia from 2010 on. Owners of both tend to search for the same things once the miles add up: soft or flaring upshifts, slipping under throttle in the middle gears, a harsh or delayed kickdown, and transmission codes for solenoid performance or lockup that keep returning. This TransGo shift kit restores the valve-body circuits behind those complaints. It is new, carries a 1-year warranty and sells for $277.99.
TransGo rates this kit for 2003-and-newer A750, A760, A761, A960 and AB60 transmissions, and the listing uses that first year. The A760E itself reached North American vehicles a little later: published applications start with the 2005 Lexus GS300 and IS models, then the 2006 GS350, with the 4.6-liter Tundra and Sequoia following for 2010. In other words, every A760E built falls inside the kit's range, but nothing about this part is specific to model year 2003.
The A760E shares its first five ratios with the A750 five-speed and adds a sixth, 0.586 overdrive. All six ratios are selected by the computer through solenoids on the valve body, and the valve body sets how firmly each clutch and brake is applied. TransGo identifies two bores that cause most of the trouble as these units age. A worn TCC relay valve bore lets the computer lose control of converter clutch apply and release, which shows up as lockup slip and rough downshifts. A worn solenoid modulator valve bore lets solenoid feed pressure stray, so every pressure-controlled shift drifts and line pressure can run high or low. The kit includes an oversized hardened steel TCC relay valve and bushing with the reamer and guides to fit it, a drop-in solenoid modulator valve assembly, and two TCC boost valve and bushing sets to match your original diameter.
Rule out low fluid first; these units are checked through a fill plug at a set temperature rather than with a dipstick, so a slow leak can go unnoticed for a long time. Next, scan for codes and watch commanded versus actual gear and lockup slip. If the solenoids measure out of range, replace them while the valve body is out with a nine-piece A760E solenoid kit or a single A760E pressure control solenoid. If shifts are harsh or late rather than soft, read our Aisin harsh and delayed shift walkthrough first, because a sticking valve can cause the opposite symptom. Burnt fluid and friction debris in the pan mean the clutch packs need attention too.
This kit covers the A760E and A760H six-speed as well as the A750E/F, A761E/H, A960E and AB60E/F, per TransGo. Published A760E applications (by calendar year) include the 2005-2013 Lexus IS rear-drive models, the 2005-2007 GS300, the 2006-2013 GS350 and the 2010-2019 Tundra and Sequoia with the 4.6-liter V8. All-wheel-drive Lexus sedans use the A960E instead, which the kit also covers. Because TCC boost bushing size varies, measure your original and install the matching one of the two supplied. When in doubt, send us your year and VIN. More parts for this family are on our Aisin transmission page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
They are close relatives. The A760E uses the same first five ratios and adds a 0.586 sixth gear, and TransGo builds one A750 kit that covers both families.
The rear-drive IS250 uses the A760E, which this kit covers. The AWD IS250 uses the A960E, which TransGo also lists. Match your TCC boost bushing to one of the two supplied.
The 4.6-liter Tundra and Sequoia use the A760E, which is within TransGo's coverage. The 5.7-liter trucks use the AB60, also covered. Send us your VIN to confirm.
It can if the cause is incorrect solenoid feed pressure from a worn modulator valve bore, which TransGo specifically targets. If a solenoid has failed electrically, it still needs replacing.
