TOYOTA/LEXUS U140/U240PRELIMINARY INFORMATION
Starting at the beginning of production for the 1998 model year for Lexus and 2000 for Toyota, a new transaxle, designated as the U140/U240 series was born. This Transaxles shift points, and shift feel are electronically controlled by a Powertrain Control Module. This is accomplished by the PCM monitoring engine load and adjusting solenoid duty cycle to match pressure rise and shift feel. The PCM also monitors the turbine and output speed sensors to calculate gear ratio and the Transmission Range Sensor for gear selection. This Technicians guide will provide theory of operation starting with a component application, continuing on thru solenoid function both mechanically and hydraulically. The manual will also provide passage identification in the Mapping section, along with full color hydraulic schematics for all ranges. Refer to the index of Figures listed on the following page for the component or information desired.

The Primary Regulator valve is controlled by the SLT solenoid, and it's spring. The PCM calculates engine load and varies the duty cycle to match pressure rise to engine load. The SLT solenoid also
controls the 2ndaryRegulator valve , to control Torque Converter pressures, and the B-3 Orifice Control valve to control the UD/B3 Brake application.

as it is turned OFF to regulate B-1 brake Apply. The PCM also will turn SL1 on briefly during the 2-3upshift to control the B-1 exhaust by draining solenoid mod pressure, which in turn allows the solenoid modpressure on the front of the B-1 lock valve to stroke the valve to the right connecting the B-1 apply pressure
to the spring side of the B-1 Control valve draining the B-1 brake. Incorrect timing of this application of this solenoid will cause a momentary bind on the 2-3 upshift.

When Solenoid SL2 is OFF Modulating Pressure will be connected to the port leading to the spring side of the C2 Lock Valve, stroking it to the left and the first land of the C2 exhaust valve. Solenoid Mod.
pressure is not capable of overcoming the spring tension and the line pressure at the spring side of the C2 Exhaustvalve so the valve stays to the left. SL2 pressure is also fed to the first land of the C2 Control valve, which
strokes the valve to the left, connecting line pressure from the 3 way check valve to the C2 Clutch.Note: The PCM controls the duty cycle of the SL2 solenoid as it is turned OFF to regulate C2 clutch Apply.

Summary: With the DSL ON, in 3rd and 4th gear, the TCC is ON, the Lockup relay valve is strokedto the left and orificed line pressure is fed to the cooler circuit. Note: when the
Lockup control valve sleeve wears, the TCC Apply circuit can leak past the valveand sleeve, to an exhaust, and cause a pressure loss in the TCC Apply Circuit.

VALVE BODY MAPPING U140/U240E
HOW TO USE THIS MANUAL:
All castings and spacer plates have been numbered so they can be identified in an oil circuit diagram. Example: 319L passage is
located in the Upper valve body (300L series). This passage can now be located in the partial oil circuit diagram shown above. Spacer
plate orifice sizes and locations are also identified in the oil circuit diagram labled Valve body Mapping.
