Five-piece shift and lockup solenoid set for the Toyota U240E and U140E valve body, replacing 35240-32010 and 35290-21010 when shifts turn harsh.
Most of the cars that end up needing this kit are four-cylinder Toyotas: a 2.4-liter Camry or Solara, a Celica or Corolla with the 1.8, a RAV4 or a Scion tC. The complaint is usually the same. The car binds up on the 1-2 shift, flares into third, shudders when the converter should be locked, or sets a P0750-series solenoid code and gets stuck in one gear. This is a five-piece set that replaces every solenoid on the U240E-family valve body in one job, so you are not left with four old coils next to one new one. The listing cross-references 35240-32010 and 35290-21010. The same solenoids are used on the V6 U140E, which shares the valve body design.
Toyota runs these transaxles from the engine computer. It reads throttle and road speed and drives five solenoids on the valve body. Three are larger linear solenoids that meter oil, and two are smaller on/off valves. Per Sonnax's firing chart for the U140/U240/U241, SL1 and SL2 are both on in first, only SL2 stays on in second, everything is off in third, and S4 comes on for fourth. A line pressure linear solenoid (Toyota names it the line pressure control solenoid) sets how hard the clutches apply. The DSL solenoid is the one most people misunderstand. Toyota's own catalog lists 35240-32010 as a 3-way solenoid, and on the U240E it is the DSL valve that runs the lock-up relay valve. It is normally closed, and besides converter lockup it also applies the B2 clutch in manual low and blocks oil to B2 in Reverse.
Do the free test first. Unplug the transmission connector, start the engine and select Reverse. With no solenoid powered, Reverse should still engage. If it does not, the DSL solenoid or the B2 control valve is the problem. If Reverse does engage, look harder at the computer. Sonnax notes that 2001-2003 RAV4s often had faulty ECMs that set this same code group, covered by Toyota bulletin TC002-06. Also reset the learned values before you buy parts, because a reset alone sometimes cures the binding. Then measure each solenoid circuit at the case connector. Our solenoid testing guide covers those checks, and Aisin harsh and delayed shifts covers the hydraulic faults that feel the same.
The listing covers the Toyota and Lexus U240E, U241E and U140E four-speeds in the Camry, Corolla, RAV4, Highlander, Estima, Sienna, Solara, Lexus ES and RX. Use that list as a starting point, not a guarantee. Toyota used several transaxles in some of those nameplates, and later model years moved to five-speeds that take different parts. Sonnax also splits these valve bodies into 1999-2005 and 2006-2012 designs, with and without a central lube feed for AWD. Check the transmission code on the plate in the driver's door jamb, and compare connector colors and bracket shapes against your old solenoids. If anything is unclear, send us your year and VIN before ordering. Other parts for these units are in our Aisin transmission parts collection.
If the fluid is burnt and full of friction material, new solenoids will not fix worn clutches. In that case, look at the U240E/U241E master rebuild kit instead.

The listing covers the U240E, U241E and U140E. They share the same valve body design and the same five-solenoid layout, but always match connector colors and bracket shapes against your old parts, or send us your year and VIN to check.
Most often the DSL solenoid. When it sticks open in Drive, the B2 clutch applies in first, and the 1-2 shift binds because too many clutches are on. Test Reverse with the connector unplugged before you replace anything.
P0750, P0753, P0755 and P0758 cover the shift solenoid circuits, and P1760 is the line pressure solenoid. On 2001-2003 RAV4s, the same codes can come from a faulty engine computer, so check before buying parts.
The 2004-2005 Camry owner's manuals specify Toyota ATF Type T-IV. Check your own manual, since later Toyota models moved to WS fluid, and set the level hot.
Yes. Reset the learned values with a scan tool. On these cars that also resets the engine adaptives. Then drive through all four gears at light throttle until the shifts feel normal.
