U660E Valve Body 2011-2016, remanufactured and ready to install. Fits the U660E. Ships fast from the USA.
This remanufactured U660E valve body is listed for the 2011-2016 model years and referenced to the Lexus ES350, which makes it a fit for the 3.5L V6 front-drive Toyota and Lexus vehicles of that period: Camry V6, Avalon, Highlander, Sienna and the ES350 itself. The usual reason people land here is a car that has started to buzz or shudder at light throttle around town, bang into a gear it used to slide into, or set a solenoid code and drop into a fallback gear. Those are classic signs of a worn valve body on this transaxle, and replacing the whole assembly is often faster and more predictable than reconditioning individual bores.
The U660E is Aisin's six-speed electronic transaxle for Toyota's V6 front-drive cars and crossovers. Pump pressure is shaped in the valve body by spool valves riding in machined aluminum bores, and the linear solenoids bolted to it, including the SL shift solenoids, the SLT line-pressure solenoid and the SLU lockup solenoid, tell those valves when and how hard to apply each clutch and brake. One feature that matters for this part is flex lockup: Toyota deliberately lets the converter clutch slip a small amount, roughly 10-30 rpm, at light and mid throttle to damp engine vibration. The lockup control valve in the valve body is constantly modulating during that mode, which is exactly why its bore wears on cars that see a lot of city driving.
Start with the fluid. A low or overfilled U660E produces the same harsh shifts and shudder, and there is no dipstick, so the level has to be checked at the overflow plug with the fluid at 185-194 F as Toyota specifies. Our U660E fluid type and capacity guide covers the check step by step. If the level and condition are good, the next stop is the U660E/U760E problems and service guide, which explains how worn solenoid modulator and lockup control bores leak line pressure and flood the solenoids, producing codes and shift complaints even when the solenoids themselves test fine electrically. A shop with vacuum-test tooling can confirm bore wear directly on the old unit.
The listing covers U660E transaxles from 2011 through 2016 and is referenced to the ES350. That span crosses a full Camry and ES redesign in the 2012-2013 model years, so do not assume a 2011 unit and a 2016 unit are identical. Compare the casting numbers, solenoid layout and harness connector on your old valve body against the photos, or send us your year, model and VIN and we will confirm before it ships. All-wheel-drive versions of these vehicles use the U660F, which is listed separately as the U660F valve body. Four-cylinder versions use the U760E, not this part. For other U660E year ranges, such as the 2007-2018 valve body, see the full U660E/U760E parts collection.
The valve body comes out from underneath after the pan, filter and solenoid harness connectors are removed. Note the position of every bolt before you pull it; the bolts are different lengths and a long bolt in a short hole can crack the casting. Install a new filter and pan gasket at the same time, such as our U660E filter and pan gasket kit for the 3.5L, so debris from the failed unit does not end up in the new one. Fill with genuine Toyota WS ATF (part number 00289-ATFWS) only, then set the level at the overflow plug at the specified temperature. Finish by clearing codes and resetting the transmission learned values with a Toyota-capable scan tool, then drive the car through several gentle full shift cycles so the computer relearns clutch fill times. If the transaxle has high mileage and burnt fluid, consider whether a U660E master rebuild kit belongs in the job instead of a valve body alone.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It fits the 2014 Camry with the 3.5L V6, which uses the U660E. The 2.5L four-cylinder Camry uses the U760E and needs a different valve body. Send us your VIN if you are not sure which engine and transaxle your car has.
Match what you see in the listing photos to your old unit. If your old solenoids are being reused, inspect the harness connectors and screens and make sure every solenoid goes back in its original position.
Often, yes. That shudder is frequently caused by a worn lockup control valve bore that cannot hold steady converter slip in flex lockup. Check the fluid level and condition first, because degraded WS fluid causes the same symptom.
Use Toyota genuine WS ATF, part number 00289-ATFWS. Do not substitute Dexron or a universal fluid. Set the level at the overflow plug with the fluid between 185 and 194 F.
Yes. Clear codes and reset the transmission learned values with a scan tool that supports Toyota, then road test with several gentle shift cycles so the computer adapts to the new valve body.
