Shift Mechanism

INFOID:0000000001327134

The A/T uses compact triple planetary gear systems to improve power transmission efficiency, simplify con-
struction and reduce weight.
It also employs an optimum shift control and super wide gear ratios. They improve starting performance and
acceleration during medium and high-speed operation.
