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 equipped with lock-up mechanism. The gear shift
device consists of 2 sets of planetary gear units, sets of 3 disc type clutches, 3sets of disc type brakes and one-
