U660E Sprag Clutch 2007-2018, used and ready to install. Fits the U660E. Ships fast from the USA.
Rebuilders looking for this part usually have a V6 Toyota or Lexus U660E six-speed on the bench with a scored or heat-damaged plate in the B1 brake, the pack that holds second and sixth gear. This listing is the genuine Toyota No.1 brake flange, part number 35676-07040, 3.3 mm thick, removed in good used condition from a 2007-2018 3.5L front-drive U660E. It is a flat steel backing plate with locating lugs on its outer edge, not a sprag or one-way clutch, whatever the listing name suggests.
ATSG's application chart for the U660E shows the B1 brake applied in second and sixth gear, working with C1 in second and C2 in sixth. B1 is a multi-plate brake: frictions and steels stacked against the case and clamped by a hydraulic piston. The flange is the thick plate at the end of that stack. The piston pushes the plates against it, so it has to stay flat and smooth, and its thickness is part of the stack height that sets the pack clearance. A warped, scored or heat-checked flange gives the frictions a poor surface to clamp, and B1 slips under load.
A slipping B1 rarely starts with the flange alone; burnt frictions are usually the cause and the flange is collateral damage.
Rule out the cheap causes first. Gears Magazine notes that wrong fluid, a carboned throttle body or a dirty MAF sensor causes flare complaints on this family, and worn valve body bores leak the pressure that applies B1. Check the fluid level hot using the overflow procedure in our U660E fluid type and capacity guide, and follow the diagnostic order in our U660E and U760E problems guide. If slip shows up only in second and sixth, the two gears B1 shares, the B1 pack is the prime suspect, and at teardown lay your old flange on a flat surface and check it for warp and scoring.
This flange came out of a 2007-2018 3.5L U660E front-drive transaxle, the V6 unit in the Camry, Avalon, ES 350, Sienna, Venza and Highlander of those years. Toyota's parts catalog uses the same number, 35676-07040, across 2007-2018 Avalon, 2007-2017 Camry, 2011-2017 Sienna, 2014-2017 Highlander and 2009-2017 Venza, and it supersedes 35676-33050. Match the part number and the 3.3 mm thickness to the flange you remove, or send us your year and VIN. More hard parts are on the U660E parts page.

No. It is the genuine Toyota No.1 brake flange, part number 35676-07040, the 3.3 mm backing plate at the end of the B1 brake pack. It has no one-way function.
Good used original Toyota part, removed from a 2007-2018 3.5L U660E front-drive transaxle. Inspect it for flatness and scoring before installation as you would any reused hard part.
Second and sixth. A slipping B1 pack shows up as a flare on the 1-2 and 5-6 upshifts or slip while in those gears.
This part came from a front-drive U660E. Match the part number and the 3.3 mm thickness to your old flange, or send us your year and VIN to confirm.
If the flange is damaged, the B1 frictions and steels almost always are too. A master rebuild kit, a filter and pan gasket kit and fresh Toyota WS fluid complete the job.
