U151E Pressure Control Solenoid, new and ready to install. Fits the U151E. Ships fast from the USA.
If your V6 Highlander, Sienna, RAV4, Camry, Solara or Lexus RX330 slides through upshifts, feels soft and lazy when you lean on the throttle, or has stored P2714 with the check engine light on, the line pressure solenoid inside the U151E is one of the first parts to check. This is a new replacement electronic pressure control solenoid, the long linear solenoid Toyota calls SLT, listed for the U150E, U151E, U151F and U250E five-speed transaxles. It is one solenoid, not the full set; if several solenoids are suspect, the seven-piece U151E solenoid kit covers the whole valve body.
The U151E (and the all-wheel-drive U151F) runs seven solenoids: SL1, SL2, SL3, S4, SR, DSL and SLT. Most of them handle individual clutch applies and lock-up. SLT has one job that touches all of them: it controls line pressure coming off the primary regulator valve. The engine computer pulses SLT at a duty ratio based on throttle position and vehicle speed, so line pressure rises when you are pulling hard and drops back when you are cruising. Toyota's own description notes that if SLT stays switched on, oil pressure goes down, clutch clamping force drops, and continued driving will burn the clutches. That is why a lazy SLT does more damage than most solenoid faults: it starves every clutch at once.
Start with the fluid level, set hot through the check plug, because low fluid on these sealed units causes the same slip. Then read every stored code. Toyota's procedure says to fix any other transmission codes before chasing P2714, since a blocked valve body, a stuck valve or a worn clutch can set the same performance code. With a capable scan tool you can run the SLT active test with a gauge installed and watch line pressure change; our line pressure testing guide shows where to tap in and what the readings mean. On the bench, the factory spec for SLT is 5.0 to 5.6 ohms at 68 F, and the valve should move and click when powered through a 21 W bulb. Our guide to testing solenoids without a factory scan tool walks through that check. Also know that Sonnax documents boost valve sleeve wear in this valve body causing soft shifts and low line rise in Drive, so a solenoid that tests good points you to the valve body instead.
This solenoid is listed for the U150E, U151E, U151F and U250E. U151E and U151F applications include the 2003-2006 Camry V6, 2004-2008 Camry Solara V6, 2004-2010 Sienna, 2004-2013 Highlander V6, 2006-2012 RAV4 V6, 2004-2006 Lexus RX330 and ES330 and the 2005-2007 Avalon. Toyota mixed transmissions inside many of those model years, and the 2007-up Camry V6 uses the six-speed U660E instead, which this part does not fit. Check the transmission code on the build label, compare your old solenoid's body, connector and mounting bracket with the photo, or send us your year and VIN and we will confirm it. Everything we carry for these units is on the Aisin transmission parts page.
SLT is mounted on the valve body, so this is a pan-off job and on many applications the valve body has to come down to reach it. Drain the fluid, pull the pan and strainer, and mark each connector before unplugging anything; the linear solenoids look alike and a swapped connector causes wrong-gear starts. Lubricate the new O-ring with clean fluid, seat the solenoid by hand and torque the bracket evenly. Refill with Toyota WS only, such as Toyota WS fluid in the 6 quart pack, and set the level hot. Clear codes and reset the transmission memory so the computer relearns clutch apply; shifts can feel firm for a few drives. If the old fluid was black or full of friction material, plan on the U151E overhaul kit rather than a solenoid alone.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is the linear pressure control solenoid Toyota labels SLT, which sets line pressure for the whole transaxle. The other six solenoids (SL1, SL2, SL3, S4, SR and DSL) handle clutch applies and lock-up and are sold together in our U151E solenoid kit.
No. Toyota lists a closed SLT solenoid, a blocked valve body, the torque converter clutch and worn clutches or brakes as causes. Fix other codes first, test the solenoid resistance (5.0 to 5.6 ohms at 68 F) and check line pressure before replacing it.
No. The 2007 and later Camry V6 uses the six-speed U660E. This solenoid is for the U151E and U151F five-speeds (and the U150E and U250E). Check the transmission code on the build label or send us your year and VIN.
Toyota WS (World Standard) fluid only. Set the level hot using the check plug procedure for your vehicle, because overfilling or underfilling a sealed unit causes its own shift problems.
Clear the codes and reset the transmission adaptive memory with a scan tool so the computer relearns clutch apply with the new solenoid. Expect slightly firm shifts for the first few drive cycles.
Yes, the U151F is listed. The front-drive U151E and AWD U151F share this valve body solenoid.
