U660E Shift Kit 2007, new and ready to install. Fits the U660E. Ships fast from the USA.
The U660E arrived in 2007 behind the 3.5L V6 in the Camry and Lexus ES 350, and the early cars are now the ones showing up with a flare between 2nd and 3rd, a slip when you push the throttle in 3rd or 4th, or a torque converter clutch slip code that comes back after every clear. This listing is the TransGo SK U660E shift kit for 2007-on units, new and made in the USA. It is a valve body repair kit: instead of buying a replacement valve body, you correct the worn valves in yours.
The part that matters most here is the solenoid modulator valve. Its job is to hold the oil supply to the shift and pressure-control solenoids at a fixed ceiling, regardless of main line pressure, so the solenoids are never fed more oil than they can regulate. When its bore wears, that ceiling moves. Feed that runs high or low makes every solenoid output high or low, so you get shift complaints, pressure codes and line pressure that will not stay where the computer wants it. TransGo's answer is a redesigned modulator valve with its own bushing, spring and end plug that works in the original worn bore, so no reaming is needed. The kit also replaces the TCC boost valve and bushing, whose wear robs the computer of clean lockup apply and release, and the B2 regulator outer valve and spring, whose leaking bore causes the 2-3 shuttle. Instructions call for opening two separator plate holes with the supplied 0.055 in. drill, a step TransGo links to running cooler.
Gears Magazine stresses scanning the whole drivetrain management system on these Toyotas, not only the transmission module, and using Toyota's Check Mode so intermittent codes set on the first occurrence. Record freeze frame data before entering Check Mode, because it erases it. Then verify fluid level hot, at 185-194 F, by Toyota's WS bulletin method. Sonnax publishes a U660E vacuum test guide that maps the critical bore wear areas, the lockup control valve among them, so you can test before teardown. Our U660E problems and service guide lays out the order to work in.
Listed for the U660E six-speed, 2007 and later. The source application covers the 2007-2012 Camry 3.5L, 2008-2010 Avalon 3.5L, 2009-2011 Venza 3.5L, 2011-2012 Sienna 3.5L, 2007-2012 Lexus ES 350 and 2010-2012 Lexus RX 350, and TransGo rates the kit through the 2018 model year. It is not for the four-cylinder U760E. Read the transaxle code on the ID plate, or send us year and VIN and we will check it. All parts for this family are on the U660E parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. Four-cylinder Camrys use the U760E or an earlier unit, and TransGo states SK U660E does not fit U760E models. This kit is for the 3.5L V6 U660E.
It is the same TransGo SK U660E part. Listings differ in the years and vehicles the source named; the kit itself is rated for 2006-2018 U660E and U660F units.
If the code comes from a worn TCC boost valve and bushing, yes; that is one of the three repairs in the kit. A failed converter or lockup solenoid will still need its own fix, so test first.
It is good practice. If your scan tool can reset the transmission learned values, do it after the valve body service so the computer adapts to the corrected pressures, then road test through every gear.
Toyota WS (World Standard) ATF, part 00289-ATFWS. Do not mix in other fluids, and check the level at 185-194 F.
