A/T Description
This automatic transaxle 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 2 sets of planetary gear units, 4 disc type clutches, a disc type brake, a band type brake and 2 one-way clutches. The gear shift is done by selecting one of 6 positions ("P", "R", "N", "D", "2" and "L") by means 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.
