Toyota U140, U240, U241 Valve Body 1998-2005

This listing is for a remanufactured U140/U240/U241 Valve Body for model years 1998-2005. Works with all variants: U140E/F, U240E/F, U241E/F, All Wheel Drive and Front Wheel Drive versions.

This valve body is better than OEM, it features many upgrades to increase reliability over the standard OEM valve body. 

The upgrades include: Oversized Pressure Regulator and Boost Valve, Clutch Apply Control Plunger/Sleeve, Lock-up Plunger Sleeve, Solenoid Modulator Valve and Secondary Regulator Valve. All solenoids are rebuilt or replaced.

Solenoid	Description	Resistance	To correctly ID the U140/U240&U241 Series see photos below.
SLT	EPC, clear/tan connector. Linear type Solenoid	4.5-6 Ohms @ room temp.
SL1	Shift (Sol. A), Clear/tan connector. Linear type Solenoid	4.5-6 Ohms @ room temp.
SL2	Shift (Sol. A), Clear/tan connector. Linear type Solenoid	4.5-6 Ohms @ room temp.
DSL	TCC, reddish brown connector. Normally closed solenoid.	11-15 Ohms @ room temp.
S4	Shift (Sol. D) black connector. Normally closed solenoid.	11-15 Ohms @ room temp.

In the above pictures on the right you will see what to look for when identifying which valve body you need. The pic with the green arrow is for the FWD version of the valve body and the pic with the red arrow is for the AWD version.                  



Please note: The linear solenoids changed in 2006. The Solenoids are smaller in diameter
and the retaining brackets are no longer permanently attached to the solenoids. In addition,
the shape of the connector changed. See RED ARROWS in photos above for differences in
connectors. Also please consult the above photos regarding the Central Lube Feed.

Binding On 1-2 shift - To determine if you have a valve body/solenoid problem or a faulty ECM, determine if you have
R with the electrical connector disconnected from the transmission.

If you DON'T have R, suspect B2 control valve is stuck on or pushed to apply position by cross leaks or DSL solenoid is
stuck open. If the transmission engages in Reverse, suspect faulty ECM. The DSL solenoid(TCC) doesn't just come on
for lock-up.

It also energizes in manual low and to inhibit R. It is normally closed and when energized allows oil pressure to stroke B2 control valve & apply B2 clutch in manual low and block oil to B2 clutch in R. If DSL is stuck open in D, B2 clutch applies in 1st like it does in manual low.

When 1-2 shift occurs w/B2 clutch applied, too many clutches are applied and the transmission binds up. If DSL is stuck
open in R, B2 control valve blocks oil to B2 clutch, inhibiting R.

The ECM(Engine Control Module) aka PCM(Powertrain Control Module) controls the engine and transmission. It's not
uncommon for RAV4 models between 2001-2003 to have faulty ECM's. Many times they have binding/harsh shifts and
produce codes P0750, P0753, P0755, P0758 and P1760. See Toyota bulletin #TC002-06, dated March 3, 2006.

NOTE: This is an adaptive learning transmission.

Learned adapts MUST be reset after overhaul or valve body replacement to avoid damage. It resets all ECM learned
adapts, not just transmission adapts. A Toyota factory scanner can reset ECM adapts.

After resetting adapts, bring transaxle to operating temp & drive vehicle at a light steady throttle through all shifts.
Repeat until shifts feel normal.

You may find that resetting shift adapts will correct binding on shifts, therefore, we recommend performing reset before
replacing an ECM. 2-3 Slip/Flair-Delayed/No Reverse- Direct clutch sealing rings wear into ring grooves of cover and
direct drum can be ring grooved.

Clearance between sealing ring and ring land is 0.003”-0.005”. Direct drums with damage where sealing rings ride should be
replaced. DON’T try to salvage drum by sanding! Another cause of pressure loss is missing/incorrectly placed washer seal
between case and rear cover.

 *DSL/TCC Solenoid is turned on to inhibit reverse

2-3 Slip/Flair-Delayed/NoReverse- Direct clutch sealing rings wear into ring grooves of cover and direct drum can be ring
grooved. Clearance between sealing ring and ring land is 0.003”-0.005”. Direct drums with damage where sealing rings ride
should be replaced. DON’T try to salvage drum by sanding! Another cause of pressure loss is missing/incorrectly placed washer seal between case and rear cover.

Slips In Reverse/No reverse - In addition to direct clutch issues, a DSL solenoid stuck "on", a B2 control valve stuck in stroked position & missing/damaged B2 seals between valve body and case can cause reverse to delay, slip or miss altogether.

Various Shift & Engagement Feel Concerns- Can be due to accumulator spring mix up. Please see chart below for correct
information.
NOTE: C1 Accumulator is for N-D engagement. C3 accumulator is for 3-4 shift. B3
accumulator effects 4-3 downshift.
