U660E Clutch Module 2007, new and ready to install. Fits the U660E. Ships fast from the USA.
A V6 Toyota or Lexus with the U660E six-speed that slips after a long drive, flares on the upshift, or shows burnt fluid in the pan is past the point where a fluid change helps. This listing is the friction module most rebuilders reach for on that job: a Precision U660E overhaul kit paired with an Exedy friction clutch module, catalogued for 2007-on transaxles. In one order you get the sealing parts for the whole unit and the lined frictions for the clutch packs, which is the core of a standard U660E rebuild.
The U660E is Aisin's six-speed front-drive transaxle built behind Toyota's 3.5L V6. It makes each ratio by applying two of its clutches and brakes at once, and the computer times those applies so one releases as the next grips. The friction plates carry the bonded lining that does the gripping. Once the lining glazes or wears thin, the clutch needs more pressure and more time to hold, so the engine flares between gears and the computer sets slip or ratio codes. The overhaul kit side of this package replaces the gaskets, lip seals, O-rings and sealing rings so the new frictions receive full apply pressure. The listing names the overhaul kit and the friction clutches; steel plates, drums, bushings and the filter are not listed, so measure and reuse or order those separately.
The U660E has several faults that feel like slipping but are not. Gears Magazine reports converter lockup shudder at light throttle between about 25 and 50 mph, which holding Manual 3 isolates, along with case bearing-bore wear and converter input-spline breakage on this unit. Sonnax's U660E vacuum test guide lists the valve body bores that wear and the symptoms each one causes, from harsh downshifts to lockup slip. Set the fluid level hot through the overflow plug first, then drop the pan. Heavy friction debris confirms a rebuild; a clean pan with a shift complaint points toward the valve body. Our U660E and U760E problems guide walks through that sorting.
This package is listed for the U660E from 2007 on. The 2007 Camry V6, Avalon and Lexus ES 350 were among the first vehicles with this transaxle, and later V6 applications include the Sienna, Highlander, Venza, RAV4 V6 and Lexus RX 350 in the years they used the U660. Some of those models used a five-speed in early years, so a model name alone is not proof. Read the code on the transaxle tag, and note that four-cylinder vehicles use the U760E and all-wheel-drive models the U660F. Send us your year, model and VIN if you want us to confirm before shipping. More parts for this family are on the U660E and U760E parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The listing pairs a U660E overhaul kit, meaning the gaskets, seals, O-rings and sealing rings, with a friction clutch module for the clutch packs. Steel plates, drums, bushings and the filter are not listed as included.
No. Four-cylinder models use the U760E, and all-wheel-drive V6 models use the U660F. This package is for the front-drive U660E. Confirm the code on your transaxle tag.
Maybe not. Clean fluid with a shift complaint often points to valve body bore wear, solenoids or converter lockup rather than worn frictions. Diagnose before tearing the unit down.
Only if they are flat, the correct thickness and free of heat bluing or glazing. Steels that have been overheated will burn the new frictions quickly, so replace any that fail inspection.
Yes. Clear the adaptive values with a scan tool after the fluid level is set hot, then drive through all six gears so the computer can learn the fill times of the new frictions.
