U151E Valve Body 2004-2014, remanufactured and ready to install. Fits the U151E. Ships fast from the USA.
If your V6 Highlander, Sienna, RAV4, Camry, Camry Solara, Avalon, Lexus ES 330 or RX 330 has started flaring between gears, engaging Drive slowly, shuddering when the converter locks, or running hotter than it should, the U151E valve body belongs near the top of the suspect list. This is a remanufactured U151E valve body for the 2004-2014 production range, cross-referenced to the U150E. It replaces the worn hydraulic control unit as one assembly, which is usually faster and cheaper than chasing individual worn bores in an old casting.
The U151E is the 5-speed automatic Toyota paired with its V6 engines in front-wheel-drive models. The valve body bolts under the case and carries the regulator valves, shift valves, accumulators and solenoids that turn the computer's commands into clutch pressure. Two circuits matter a lot on high-mileage V6 units. The secondary pressure regulator valve oscillates constantly to set converter and lockup pressure, and Sonnax reports that this motion wears both the valve and its bore until lockup pressure becomes unstable. The accumulator pistons cushion each clutch apply, and wear in their cast aluminum bores lets apply oil exhaust before the clutch is fully on.
Start with a scan for codes and a fluid check. A lockup or solenoid code that matches the symptoms above, together with fluid that is still reasonably clean, points toward the valve body and solenoids. If the shudder only appears during lockup and disappears when you lightly press the brake to unlock the converter, the lockup control side is the likely cause rather than the engine. Heavy debris or a slip present in every gear means the clutches are worn too, and the job becomes a rebuild with this valve body included. If the wiring has been chafed or a solenoid connector is corroded, rule that out first; the U151E internal wiring harness is a far cheaper fix if it is the actual fault.
This valve body is listed for the U151E from 2004 to 2014. Factory U151E applications in that window include the 2004-2006 Camry V6, 2004-2008 Camry Solara V6, 2004-2010 Sienna, 2004-2013 Highlander V6, 2005-2007 Avalon, 2006-2012 RAV4 V6, and the 2004-2006 Lexus ES 330 and RX 330. The all-wheel-drive versions of these vehicles use the U151F, and earlier 2001-2003 units used larger solenoids that do not interchange; for those, see our U151E valve body for 2001-2003. Confirm the transmission code on your case and match the casting and solenoid connectors on your old valve body, or send your year, model and VIN for a fitment check. More Toyota and Aisin parts are in the Aisin transmission collection.
Drain and drop the pan, remove the filter, and tag each solenoid connector before removing the old body. Install the replacement, torque the bolts in sequence, and fit a new filter and pan gasket. Most of these vehicles specify Toyota WS ATF; confirm the fluid on your owner's manual for your exact year, refill, and set the level hot with the engine running. Clear the adaptive values and let the computer relearn over several drives. A tired linear solenoid can mimic a bad valve body, so the U151E pressure control solenoid is worth replacing on a high-mileage unit, and if delayed engagement persists with good line pressure readings, inspect the U151E pump as well.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Front-wheel-drive V6 applications including the 2004-2006 Camry, 2004-2008 Camry Solara, 2004-2010 Sienna, 2004-2013 Highlander, 2005-2007 Avalon, 2006-2012 RAV4, and the 2004-2006 Lexus ES 330 and RX 330. AWD versions use the U151F.
No. The 2001-2003 units use larger solenoids and a different valve body. Order the 2001-2003 listing for those years, or send your VIN if you are unsure which generation you have.
Yes. Wear in the secondary pressure regulator valve and its bore makes lockup pressure unstable. Low pressure lets the converter clutch slip and shudder, and high pressure can make lockup harsh.
The U150E is the related 5-speed unit in the same family. The reference helps match castings, but fitment should still be confirmed by the code on your case and the connectors on your old valve body.
Yes. Clear the adaptive values with a scan tool and drive through normal light and moderate throttle shifts so the computer relearns shift timing for the new valve body.
