Automatic Transmission - Control System - Mechanism & Function
SELECT LEVER
The automatic transmission select lever can be moved to any of the 4 ranges and the transmission enters
sports mode when the lever is moved laterally from D range, and further switches to sports shift mode
(manual mode) when the lever is moved forward ("+" direction) or rearward ("-" direction).
The select lever makes shift direction (longitudinal) movements as well as select direction (lateral)
movements. The select lever is guided by a gate to make these movements.
In the sports shift mode, the transmission upshifts when the selector lever is moved forward ("+"
direction) and downshifts when the lever is moved rearward ("-" direction).
To transmit movements of the select lever to the transmission, a select cable is used.
The select lever mechanism has a detent spring. It ensures more precise positioning of the select lever.

SHIFT LOCK AND KEY INTERLOCK SYSTEM
GENERAL
To increase safety during standing start, the shift lock system prevents movement of the select lever from the
"P" position to any other position unless the brake pedal is depressed. This system is also provided with a key
interlock function which prevents removal of the ignition key from the key cylinder unless the selector lever is
placed in the "P" position.

SHIFT LOCK SYSTEM OPERATION
The shift lock system has a solenoid-operated plunger (1). With the select lever in the P position, the plunger
remains extended, holding the lock arm (2) in its pushed out (locking) position. When the brake pedal is
depressed with the ignition switch in either the ON or START position, the solenoid is energized and the
plunger is retracted. This causes the lock arm to lift to the select lever release position. The select lever now can
be moved to any other position. The P position of the select lever is detected by the inhibitor switch (3).

KEY INTERLOCK FUNCTION
When the select lever is at any position other than P, the solenoid is energized and its guide pin extends to
hold the lock pin in its pushed out position. Held in its extended position, the lock pin interferes with the
stopper portion of the rotator which turns together with the ignition key. Thus, the ignition key cannot be

rotated to the "LOCK" position.

When the select lever is moved to "P", the "P" position switch in the select lever assembly operates,
deenergizing the solenoid. As the push force of the guide pin is removed, the return spring moves the lock
pin toward the solenoid and the lock pin becomes clear of the rotator stopper. Then the key can be rotated
to the LOCK position and removed from the ignition switch.
