Shift Mechanism

Shift Mechanism

The RE4R03A and RE4R01A automatic transmissions use compact, dual planetary gear systems to improve power-transmission efficiency, simplify construction and reduce weight.

They also employ an optimum shift control and superwide gear ratios to improve starting performance and acceleration during medium and high-speed operation.

Two one-way clutches are also employed: one is used for the forward clutch and the other for the low clutch. These one-way clutches, combined with four accumulators, reduce shifting shock to a minimum.
