U151E Pressure Control Solenoid 2009, remanufactured and ready to install. Fits the U151E. Ships fast from the USA.
A 2009 Toyota Highlander, RAV4 or Sienna with the V6 and the U151E five-speed that slurs from 2nd to 3rd, flares on the highway kickdown or sets P2714 is a classic candidate for a weak SLT solenoid. This listing is that solenoid: the Aisin-made SLT, Toyota part number 35290-33020, with the red label that marks the 5 to 6 ohm coil. Our spec sheet lists it as remanufactured and tested. It is one solenoid, not the full valve body set.
The U151E is Toyota's V6 five-speed transaxle, and the U151F is its all-wheel-drive twin. Of the seven solenoids in its valve body, the SLT has one job: it tells the primary regulator valve how much main line pressure to build. The transmission computer feeds SLT a varying duty signal based on throttle and load, so pressure climbs when you pull a trailer or merge hard and backs off during light cruising for smoother shifts. Toyota's repair manual is blunt about the failure mode: if SLT is stuck on, line pressure drops and continued driving burns the clutches. That is why an SLT problem caught early is a solenoid job, and caught late is a rebuild.
First make sure the fluid is full. Toyota sets U151E level through the check plug with the fluid at temperature, and a low level alone produces the same flare. Next read all codes, because Toyota's P2714 diagnosis also lists a stuck valve body and worn clutches as causes. Then check the solenoid: Toyota specifies 5.0 to 5.6 ohms at 68 F across the SLT terminals, and the solenoid should operate when energized through a 21 W bulb. Our guide to testing solenoids without a factory scan tool walks through that bench test. If you have access to a pressure gauge, the line pressure testing guide will tell you whether pressure actually rises with throttle. A good solenoid with low line rise points at a worn bore in the valve body, a known U151E/F issue that Sonnax addresses with a boost valve kit.
For the 2009 model year, the U151E and U151F were used in the Toyota Highlander V6, RAV4 V6 and Sienna 3.5L, in front-drive and all-wheel-drive form. The supplied compatibility list also names the 2009 Camry, Avalon, Corolla, Matrix and Lexus ES350. Those cars did not use the U151E that year: the Camry V6, Avalon and ES350 had moved to the six-speed U660E, and the Corolla and Matrix use four-cylinder transaxles. Pull your old solenoid and match the 35290-33020 number and red label, or send us your year and VIN and we will confirm. Our Aisin transmission collection has more parts for this family, and the 2007 U151E SLT solenoid page covers the earlier V6 applications.
SLT comes out from underneath with the pan and filter removed. Unplug the internal connector, remove the retaining bolt and draw the solenoid straight out of its bore without levering on the coil. Put fresh ATF on the new O-ring and seat it by hand before torquing the retainer. Use Toyota WS fluid only, for example the genuine Toyota ATF WS six-quart pack, and set the level hot through the check plug. Clear codes and reset learned values with a scan tool if yours supports it, then drive through several full shift cycles. On a high-mileage 2009 with more than one solenoid code, the U151E solenoid kit replaces the entire set in the same pan-off job.

No. For 2009 those cars use the six-speed U660E, which takes different solenoids. This SLT solenoid is for the five-speed U151E and U151F found in the 2009 Highlander V6, RAV4 V6 and Sienna.
It replaces Toyota 35290-33020, the SLT line pressure solenoid with the red label coil marking. Match that number on the solenoid you remove.
P2714 is the SLT pressure control solenoid performance code. Toyota lists the solenoid, a stuck valve in the valve body and worn clutches as possible causes, so check fluid level and test the solenoid before replacing parts.
Measure resistance across its terminals; Toyota's spec is 5.0 to 5.6 ohms at 68 F. Then energize it through a 21 W bulb and confirm it operates. Out of range or no movement means replace it.
Toyota ATF WS only. Fill and check the level at operating temperature through the check plug as Toyota specifies.
