U250E Shift Kit, new and ready to install. Fits the U250E. Ships fast from the USA.
If your four-cylinder Camry or Solara flares on the 2-3 upshift, binds going into 4th, slips under throttle in 3rd or 4th, or keeps setting torque converter clutch slip codes even after a reseal, the problem is often worn valves in the U250E valve body. This listing is the TransGo SK U151 Shift Kit, a valve body repair kit TransGo builds for the U150, U151 and U250 family. Its instructions list the U250E five-speed in the 2.4L Camry, Solara, Corolla and Matrix.
The U250E is a five-speed transaxle that shifts with linear solenoids. The SL1, SL2 and SL3 solenoids each control a clutch or brake, and the SLT sets line pressure. Those solenoids can only work as well as their fluid supply. A solenoid modulator valve limits the pressure feeding them, much like a solenoid regulator does in other units. When its bore wears, solenoid feed goes too high or too low, and so does every clutch apply pressure. TransGo names two more wear points: the TCC boost valve and bushing, which control how fast lockup applies, and an aluminum clutch apply control valve that sticks in its bore and spoils the 2-3 shift.
The kit replaces all three with drop-in parts. You get a hardened steel TCC boost valve and bushing, a new solenoid modulator valve with spring and bushing that runs in the existing worn bore, and a hardened steel clutch apply control valve. A .055 inch drill bit is included for the separator plate lube corrections in the instructions. It is a repair kit, not a firm-shift kit.
Do a transmission memory reset first. GEARS Magazine notes that many U150/U250 slip and bind calls come in on units that were already rebuilt, and a reset with a capable scan tool is step one. Next, back-probe the SL1, SL2 and SL3 circuits at the case connector and check that the voltage changes on each shift, to rule out the computer and its grounds. TransGo adds a useful clue: a bind on the 3-4 shift or a burned forward (C1) clutch calls for a new SL3 solenoid. If the clutches are already burned, the kit alone will not save the unit. Our Aisin harsh and delayed shift guide covers the wider checks.
TransGo's instructions list the U250E in the 2005-2009 Camry 2.4L, the 2006-2008 Solara 2.4L, and the 2009 Corolla and Matrix 2.4L. The same kit also covers U151E and U150E V6 applications, which is why the box is marked SK U151. Watch the 2005 cutover: some 2005 four-cylinder Toyotas used the four-speed U241E, and this kit does not fit it. Read the model code on the transaxle tag or send us your year and VIN before ordering. Other Toyota-Aisin parts are in our Aisin transmission collection.
The valve body has to come out and be split. TransGo says to mark every check ball, retainer and small part before you lift the plates, because layouts vary by year. Before installing the new solenoid modulator bushing, insert the original valve backwards and stroke it until any ridge in the bore is gone. If the new bushing binds, stop and clean the bore again. When you test the solenoids, the SR, S4 and DSL on/off units should read 11 to 15 ohms. Identify the linear solenoids by their porting, not by connector color. Assemble the C2, C3 and B3 accumulators correctly, since a mixed-up spring causes engagement complaints. If the unit needs more than a valve body service, pair this kit with our U250E master rebuild kit, or replace a scored casting with a remanufactured U250E valve body. A weak line pressure solenoid can be swapped with our U250E pressure control solenoid. Refill with Toyota WS fluid, check the level at temperature, then reset transmission memory and drive several full shift cycles.

TransGo builds one kit for the U150, U151 and U250 family and names it after the U151. The U250E is the four-cylinder member of that family, and TransGo's instructions list the 2005-2009 Camry 2.4L, 2006-2008 Solara 2.4L and 2009 Corolla and Matrix 2.4L.
It targets the clutch apply control valve and solenoid modulator wear behind many 2-3 flare and bind complaints. Do a memory reset and check the SL solenoids first, and know that burned clutches still need a rebuild.
The kit goes in the valve body, which comes out with the pan off. You do have to split the valve body and drill the separator plate holes the instructions call for, so plan on careful bench work.
Only if it has the U250E. TransGo lists the Solara 2.4L from 2006 to 2008. Many 2005 four-cylinder models used the four-speed U241E. Check the transaxle tag or send us your VIN.
Refill with Toyota WS fluid and check the level at operating temperature. Then reset the transmission memory with a scan tool and drive through several full upshift and downshift cycles so the computer relearns.
