Shift Mechanism

Shift Mechanism
The automatic transmission uses compact, dual planetary gear systems to improve power-transmission efficiency, simplify construction and reduce weight.

It also employs an optimum shift control and superwide gear ratios. They 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.

P and N Positions




* P Position
Similar to the N position, no control members operate. The parking pawl interconnected with the select lever engages with the parking gear to mechanically hold the output shaft so that the power train is locked.
* N Position
No control members operate. Power from the input shaft is not transmitted to the output shaft since the clutch does not operate.
