U660E Master Rebuild Kit 2006-2011, new and ready to install. Fits the U660E. Ships fast from the USA.
The first U660E transmissions went into production in 2006 for the 2007 model year, which means the earliest Camry V6 and Lexus ES350 units are now well past the mileage where clutches give out. If your early six-speed slips, flares between gears or leaves burnt friction material on the pan magnets, this master rebuild kit is sized for exactly that generation: it is listed for U660E transmissions from 2006 through 2011 and cross-referenced to the U660F.
Inside the U660E, six forward ratios are produced by two clutches (C1 and C2), three brakes (B1, B2, B3) and a one-way clutch (F1), according to ATSG's application chart. The TCM applies them through linear solenoids and keeps adjusting pressure as plates wear. On a 2006-2011 unit that has spent years compensating, the plates are often thin, glazed or burnt in more than one pack by the time the slip becomes obvious. This kit replaces the frictions and steels and supplies the gaskets and seals to reseal the unit. From the kit photo, that includes friction and steel plates, valve body separator gaskets, the oil pan gasket, lip seals, O-rings and sealing rings. Hard parts are not included, and on a unit this age they deserve a close look.
Early units are the ones most likely to have had the wrong fluid added at some point, and Toyota issued a 2013 bulletin specifically on setting WS fluid level in U660E/F transmissions. Check the level hot through the overflow plug as described in our U660E fluid type and capacity guide before deciding anything. Then separate shudder from slip: a 25-50 mph shudder is usually the converter or the lockup valves, and our U660E and U760E service guide explains testing it in Manual 3rd, where flex lockup is disabled. Many early vehicles also received TCM programming updates for lockup complaints, so ask a dealer to check for one. If the clutch slip remains, the rebuild is justified.
This kit is listed for U660E transmissions built from 2006 to 2011, with the U660F as a cross-reference. ATSG's application list for that period includes the Camry, Avalon, Highlander, RAV4, Sienna and Venza along with the Lexus ES350 and RX350, worldwide. US availability varied, and many of those nameplates used other transmissions with four-cylinder engines or in some years, so read the tag on your transmission and confirm U660E or U660F. Plate counts changed over production; compare as you disassemble or send us your year, model and VIN. For units newer than 2011, see the undated U660E master rebuild kit, and browse the full U660E collection.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Production of the 2007 model year Camry V6 and Lexus ES350 began in calendar 2006, so the 2006-2011 range covers the first-generation units from the start.
It is listed for 2006 through 2011. For later units, check our undated U660E master rebuild kit and confirm the transmission tag.
From the kit photo: friction plates, steel plates, valve body separator gaskets, the oil pan gasket, lip seals, O-rings and sealing rings. Drums, bushings, planetaries and the valve body are not included.
Toyota Genuine ATF WS, with the level set through the overflow plug at 185 to 194 F fluid temperature, as described in Toyota's 2013 level-adjustment bulletin.
The kit is cross-referenced to the U660F, so the internal soft parts are common. Confirm your transmission tag before ordering.
