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 super wide 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.

POWER TRANSMISSION
"N" and "P" Positions





- "N" position
No control members operate. Power from the input shaft is not transmitted to the output shaft since the clutch does not operate.
- "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.
