SHIFT CONTROL MECHANISM
1. General
A gate type shift lever that uses a shift control cable has been newly adopted in conjunction with the
installation of the 5-speed automatic transaxle.
With the gate type, the shift lever button and the overdrive switch of the straight type shift lever have been
discontinued. Similar functions are achieved through a single-shift operation (fore-aft and side-to-side).
A shift lock system consists of the key interlock device and shift lock mechanism, has been adopted.
2. Shift Lock System
General
A shift lock system of the key interlock device and shift lock mechanism, that prevents the unintended
operation of the shift lever has been provided.
A mechanical key interlock device that uses the key lock cable has been adopted.
An electrical shift lock mechanism, in which a shift lock solenoid and a shift lock ECU are integrated, has
been adopted.

Key Interlock Device
1) General
This device will not allow the ignition key to be turned to the LOCK position or to pull out the ignition
key unless the shift lever is moved to the P position.
This device, in which the shift lever and the key cylinder are connected via the key lock cable,
mechanically limits the movement or the ignition key through the movement of the shift lever.
2) Construction and Operation
The key cylinder contains a cam and a lock pin that move in unison with the ignition key. In addition,
a key lock cable and a lock plate are placed above the lock pin.
When the driver moves the shift lever, the lock plate slides to restrict the movement of the lock pin,
which in turn, restricts the movement of the ignition key.
Shift Lock Mechanism
The shift lock mechanism prevents the shift lever from being shifted out of the “P” position to any other
position unless the ignition switch is turned ON and the brake pedal is pressed.
A shift lock override button, which manually overrides the shift lock mechanism, is provided.

U150E AUTOMATIC TRANSAXLE
DESCRIPTION
The U150E automatic transaxle (hereafter referred to as “A / T”) is a newly developed, compact and high-
capacity 5-speed Super ECT (Electronically Controlled Transaxle).
Based on the U140E A / T of the ’01 ES300, this U150E A / T has been changed into a 5-speed to improve
fuel economy and dynamic performance.
– Main Changes (from U140E A / T) –
Direct & O/D (C
0
) clutch and 2 solenoid valves (SL3, SR) have been adopted.
Fluid passages have been changed for the 5-speed applicaton.
