U151E Pressure Control Solenoid 2004, remanufactured and ready to install. Fits the U151E. Ships fast from the USA.
For 2004 Toyota put its new V6 five-speed, the U151E, behind the 3.0L and 3.3L engines across a big part of the lineup: the Camry V6, the redesigned Sienna, the Highlander V6, the Camry Solara V6 and the Lexus ES330 and RX330. Twenty years on, many of those vans and SUVs are showing the same complaint: a slip or flare between gears, soft shifts once the fluid is hot, and sometimes a P2714 code. One of the first parts to check is the SLT solenoid that controls line pressure. This listing is that solenoid, Toyota part number 35290-33020, the Aisin unit with the red label that marks the 5 to 6 ohm coil. Our spec sheet lists it as remanufactured and tested. It is a single solenoid.
Think of SLT as the volume knob for the whole hydraulic system. The other six solenoids in the valve body decide which clutch applies and when the converter locks, but they all work from the line pressure that SLT sets. The computer drives SLT with a variable duty signal, and the solenoid in turn sends a signal pressure to the primary regulator valve. Under light throttle the pressure stays modest so the shifts are smooth; under heavy throttle, a full load of passengers or a trailer, it rises so the clutches can hold the torque of the V6. Toyota's manual is plain that an SLT stuck on drops line pressure and burns the clutches if the vehicle keeps being driven. On a heavy 2004 Sienna or Highlander, that is how a slipping solenoid becomes a rebuild.
Rule out low fluid first. The U151E is checked hot at the check plug, and being a quart low creates the same slip. Next, read every stored transmission code; Toyota lists valve body problems and clutch wear as other causes of P2714. Then test the solenoid: 5.0 to 5.6 ohms at about 68 F, and the valve should move when you power it through a 21 W bulb. Our guide to testing solenoids without a factory scan tool covers that bench test. To tell a solenoid problem from a mechanical one, read shift flare vs. slip; a flare that gets worse as pressure demand rises points toward SLT or a worn regulator bore, while a steady slip in one gear points to that clutch.
In the 2004 model year this solenoid fits the U151E front-drive and U151F all-wheel-drive five-speeds in the Camry V6, Camry Solara V6, Sienna, Highlander V6, Lexus ES330 and Lexus RX330. The four-cylinder 2004 Camry, Solara and Highlander use the four-speed U241E, which takes a different solenoid set, and the 2004 Avalon is not a U151E vehicle; the five-speed came to the Avalon with the 2005 redesign. The reference chart on this listing also lists later models such as the ES350 and Corolla, which use different transaxles, so go by the part rather than the chart. Match 35290-33020 and the red coil label on the solenoid you take out, or send us your year and VIN to check. Other parts for this family are in our Aisin transmission collection.
Drain and drop the pan, remove the oil strainer, then take out the SLT retainer bolt and pull the solenoid straight from the valve body. Do not pry on the coil housing. Lubricate the new O-ring with WS fluid, push the solenoid fully home, refit the retainer and harness connector, and torque the bolts to spec. A 2004 unit that has never been serviced is worth a fresh strainer and pan gasket at the same time. Refill only with Toyota WS, for example the genuine Toyota ATF WS six-quart pack, and set the level hot at the check plug. Clear the codes and reset learned values if your scan tool allows. If more than one solenoid code is stored, the seven-piece U151E solenoid kit covers the whole valve body for one pan drop, and if the clutches are already burnt the U151E overhaul kit is the real fix.

No. Four-cylinder 2004 models use the four-speed U241E. This SLT solenoid is for the V6 five-speed U151E and U151F.
Our spec sheet lists this one as remanufactured and tested. It replaces Toyota 35290-33020 and has the red label 5 to 6 ohm coil.
Yes. The U151F all-wheel-drive transaxle uses the same SLT solenoid as the front-drive U151E. Check the number on your old part to be sure.
P2714 for SLT performance and P2716 for an SLT circuit fault. A low fluid level, stuck valve or worn clutches can also set P2714, so check those first.
Clear the codes and reset the learned shift values if your scan tool supports it, then drive several full shift cycles so the computer can adapt.
