U660F Valve Body 2007-2011, remanufactured and ready to install. Fits the U660F. Ships fast from the USA.
Early U660F six-speed automatics built from 2007 through 2011 share a known wear pattern: the valve body bores and shift solenoids break down faster than later production runs, and owners usually notice it first as a hard, banging 1-2 shift or a shudder under light throttle at highway cruise. This remanufactured valve body is matched to the 2007-2011 casting specifically, so the replacement drops in without guessing which internal revision your Camry, RAV4, Highlander, Sienna or Lexus ES or RX actually carries.
Inside the U660F, line pressure gets routed to each clutch pack and band through a stack of precision bores and spool valves, and the same casting carries the shift and pressure control solenoids the computer fires to time every gear change. On the 2007-2011 production run those bores and solenoid seats are the first things to lose tolerance with age and heat cycling, which is why a car with well over 100,000 miles on the original unit starts shifting differently even though nothing else in the drivetrain has changed.
Shift manually into 3rd gear and hold the same cruise speed where the shudder shows up. If it disappears, the complaint usually traces to the torque converter clutch circuit rather than the whole valve body - see our U660E/U760E problems and service guide for the full isolation steps. Before ordering, also confirm the fluid was serviced and leveled correctly; because this transaxle is checked by temperature instead of a dipstick, our U660E fluid type and capacity guide covers the exact 185-194F window the level check requires.
This valve body is built to the casting used specifically on 2007-2011 production U660F and U660E/U760E units, which Toyota revised again after 2011 - a later-year unit uses a different internal layout and will not swap in cleanly. Confirm your build year and casting number against your old part before ordering, especially if your vehicle sits right at the edge of the window. The full U660 transmission parts collection lists the later-year valve bodies if your car falls outside 2007-2011.
Pull the pan and filter before removing the valve body so contamination from the worn unit cannot carry into the new one, then disconnect the internal solenoid harness and remove the mounting bolts in a crossing pattern to keep the separator plate and check balls from shifting out of place. Torque the bolts back down evenly to spec, fit a new filter and pan gasket, and refill with Toyota Genuine WS ATF set to level at the correct fluid temperature. Run the adaptive relearn afterward with several light-throttle upshifts and downshifts - a U660E shift kit is worth installing alongside this if the old unit also showed delayed engagement, and a fresh U660E pump is worth checking if line pressure was already low before the valve body failed.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Toyota revised the internal casting and solenoid layout again after 2011. This valve body is built to match the earlier 2007-2011 production run, so a later-year unit will not interchange cleanly even though both carry the U660F designation.
Shift manually into 3rd gear at that speed. If the shudder goes away, it usually points at the torque converter clutch circuit specifically rather than the valve body as a whole - see our U660E/U760E problems guide for the full test.
Toyota Genuine WS ATF, leveled at a fluid temperature of 185-194F rather than checked with a dipstick.
Yes - run the adaptive relearn with several light-throttle upshifts and downshifts so the TCM recalibrates clutch apply timing to the new unit.
A fresh filter and pan gasket at minimum. If the old unit also showed delayed or harsh engagement, a shift kit or a pump check is worth doing in the same service.
This valve body is remanufactured and bench-tested, with a 1-year warranty.
