AUTOMATIC TRANSMISSION (4 A / T) 7B1-3
GENERAL DESCRIPTION
This automatic transmission is a full automatic type with 3-speed plus overdrive (O / D).
The torque converter is a 3-element, 1-step and 2-phase type and is equipped with an electronically controlled
lock-up mechanism. The gear shift device consists of 3 sets of planetary gear units, 3 disc type clutches, 4 disc
type brakes and 3 one-way clutches. The gear shift is done by selecting one of 6 positions (“P”, “R”, “N”, “D”, “2”
and “L”) of the select lever installed on the floor. On the shift knob, there is an overdrive (O / D) off switch which
prevents shift-up to the overdrive mode. The optimum line pressure of fluid is obtained based on throttle pressure
of fluid. The throttle pressure of fluid which corresponds to engine load (engine torgue) is adjusted by electronic
controlled linear solenoid.
