Shift Mechanism

INFOID:0000000009480466

The automatic transmission uses compact triple planetary gear systems to improve power-transmission effi-

ciency, simplify construction 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.
