Complete 7-piece remanufactured solenoid set for the Toyota U250E and U151E 5-speed automatics: shift, lock-up and line pressure solenoids.
A Camry, Avalon, ES330 or RX that bangs into third, flares on the 3-4 upshift, or shudders at highway cruise with a solenoid code stored usually ends up on a lift with the pan off. This is a remanufactured seven-piece set that replaces every solenoid on the valve body of the Toyota U250E and U151E five-speed automatics in one job: four long-spool linear pressure solenoids and three compact on/off solenoids. The listing describes the set as the shift solenoids plus the lock-up solenoid, the lock-up pressure control solenoid and the line pressure control solenoid. Each piece is inspected and calibrated, and it may show light surface marks from previous service.
These Aisin-built five-speeds are fully electronic. The on/off solenoids switch oil to move shift valves, and the linear solenoids meter pressure in fine steps so the computer can control exactly how quickly each clutch applies and releases. One linear solenoid sets line pressure for the whole transmission, which decides how hard every clutch is clamped. Another sets torque converter lock-up apply. When a linear solenoid gets sluggish from varnish or worn bore contact, the computer still commands the right current, but the pressure that reaches the clutch is wrong. Too little and the clutch slips and burns; too much and the shift slams. Lock-up control wears the same way and shows up as a shudder or a converter that drops in and out.
Check the fluid level with the engine running and the fluid at temperature, because a low level on these units causes slipping that looks like a pressure fault. Read the codes and note which circuit is named. A circuit code can be a chafed harness or a loose connector, so measure the solenoid at the transmission case connector and again at the computer before you condemn the solenoid. Our solenoid testing guide covers resistance and activation checks without a dealer tool. If the complaint is a soft or harsh feel with no codes, a gauge on the line pressure tap tells you far more; see our line pressure testing guide. Sonnax documents lock-up control valve and boost valve bore wear in this valve body family, and new solenoids will not cure a worn bore.
The listed vehicles are the 2003-2009 Camry 2.4L, 2003-2006 Camry 3.0L, 2005-2006 Camry 3.3L, 2006-2007 Avalon 3.5L, 2004-2006 Lexus ES330 and RX330 3.3L, and 2007-2008 RX350 3.5L. Toyota fitted different transmissions inside those same model years, and many earlier four-cylinder Camrys left the factory with a four-speed U241E. This set is for the U250E and U151E five-speeds only; it is not for the U140E or U240E four-speeds or the U760E six-speed. Read the transmission code on the case tag or the build label before ordering, or send us your year and VIN and we will confirm it. All of our Aisin parts are on the Aisin transmission parts page.
Drain the fluid, drop the pan and remove the strainer. Unplug the solenoid connectors, then unbolt each solenoid from the valve body and keep track of which bore each one came from, since the linear solenoids look alike but do not share a job. Lube the new O-rings with clean ATF, seat each solenoid by hand without forcing it, and torque the brackets evenly. Fit a new strainer and pan gasket and refill with Toyota WS fluid only, then check the level hot. Clear codes and reset the transmission adaptive values so the computer relearns shift timing with the new parts; shifts can feel firm for the first few drive cycles. If the fluid came out burnt or full of friction material, the clutches have been slipping and a U250E master rebuild kit belongs on the list. For a single bad line pressure solenoid only, the separate U151E pressure control solenoid is also available.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Only if it has the five-speed U250E. Many four-cylinder Camrys of that era came with the four-speed U241E, which uses different solenoids. Read the code on the transmission tag or send us your VIN.
Toyota WS (World Standard) ATF. Do not substitute a generic multi-vehicle fluid; the solenoid calibration and shift timing are set around WS viscosity.
Yes. Clear codes and reset the transmission adaptive values with a scan tool, then drive normally through all gears so the computer relearns clutch apply with the new solenoids.
The linear solenoids wear together from the same fluid, and the pan has to come down either way. Replacing the full set removes the guesswork and avoids a second teardown for the next one to fail.
It can be either. A lock-up pressure solenoid that cannot hold steady pressure causes shudder, but so does a worn lock-up control valve bore or a glazed converter clutch. Check the fluid and codes first, and if the shudder stays after new solenoids, look at the valve body.
