U140E Master Rebuild Kit, new and ready to install. Fits the U140E. Ships fast from the USA.
A Toyota Camry V6, Highlander, RAV4 or Lexus RX 300 with a U140-series four-speed that slips on the 2-3 shift, has gone slow or soft into Reverse, or smells burnt at every fluid check has usually worn more than one clutch pack. This new U140E master rebuild kit is built for that job: the friction plates and steel plates for the clutch packs, the cork pan gasket, valve body separator gaskets, lip seals, O-rings and sealing rings, so the whole transaxle is resealed and reclutched in one teardown. The listing is also referenced to the U140F, the all-wheel-drive version that shares the same gear ratios.
The U140E is a front-drive four-speed Aisin-built transaxle with 3.938, 2.194, 1.411 and 1.019 forward ratios. The ECM runs it with SL1, SL2 and S4 shift solenoids plus a DSL solenoid that handles lockup and also applies the B2 clutch in manual low and blocks it in Reverse. That means the clutches and the hydraulic circuit feeding them are tightly linked: a pack that has lost material, or a sealing ring that leaks apply oil, both look like slipping to the driver. A master kit replaces the friction material and every rubber and Teflon seal in those circuits at once, so the rebuilt unit holds pressure the way the computer expects it to.
Not every U140E complaint needs this kit. Sonnax and the TASC Force describe a quick test for the 1-2 bind-up: unplug the transmission connector and select Reverse. If it moves, the hard parts are likely fine and the ECM side is suspect; on 2001-2003 RAV4s, codes P0750, P0753, P0755, P0758 and P1760 with binding shifts are covered by Toyota bulletin TC002-06. Reset the learned adapts before condemning anything. If there is no Reverse with the plug off, or the fluid is burnt with debris, the internals are worn. Our slipping diagnosis guide and Aisin slipping-under-load guide walk through pressure and stall checks before you commit to the teardown.
The U140E was used in the 1999-2001 Lexus ES 300, the 1999-2003 Lexus RX 300 (FWD), the 2001-2003 Highlander V6 and the 2002-2004 Camry V6. The U140F, which this kit also references, went into the AWD RX 300 and Highlander and the 2001-2012 RAV4 AWD. Valve bodies changed for 2006, and FWD and AWD units differ in lube feed, so match the transmission code on the case tag, or send us your year and VIN to confirm before ordering. More Toyota and Lexus parts are in our Aisin transmission collection.

The listing references the U140F alongside the U140E, and both share the same gear ratios. AWD units differ in lube feed and some housings, so confirm the code on your transmission tag or send us the year and VIN before ordering.
Often not. Unplug the transmission connector and try Reverse. If it engages, suspect the ECM or learned adapts first; a DSL solenoid stuck open or a stuck B2 control valve can also cause the bind. Reset the adapts before replacing hard parts.
Worn direct clutch sealing rings and a ring-grooved direct drum are the common causes, along with a missing case-to-rear-cover washer seal or damaged B2 seals. The seals are in this kit; a grooved drum must be replaced.
Use the Toyota ATF listed in your owner's manual or on the dipstick for your year. Do not mix in a generic multi-vehicle fluid.
Yes. The ECM learned adapts must be reset after an overhaul or valve body replacement, then the transaxle is warmed up and driven at light throttle through all shifts until they feel normal.
