(6) 4th Drive Gear (1.386)
Front sun gear locked, rear planetary gear and rear sun gear rotated
When the overdrive clutch (OD/C) operates, the carrier is engaged with sun gear in rear planetary
gear set and the power with 1:1 ratio flows to the front planetary gear locked with sun gear after
passing through the rear & front annulus gears.
At this moment, by operation of speed-reduced annulus gears and carrier in 1:1 ratio, the middle sun
gear in middle planetary gear set increases its speed without load (idling). -

(7) 5th Drive Gear (1.000)
Middle & rear planetary gears, middle sun gear and rear sun gear rotated
The rotating ratio of 1;1 is transferred to middle annulus gear (front planetary gear) because the
middle planetary gear and sun gear in middle planetary gear set rotate simultaneously.
At this moment, the rear planetary gear set rotates in 1:1 ratio (same in 4th gear). However, the front
planetary gear set is not related to that, and the front sun gear rotates without load (idling) in 1:1 ratio. -

(8) 6th Drive Gear (0.722)
Middle planetary gear rotated, middle sun gear locked
When the sun gear is locked in middle planetary gear set and the planetary gear rotates, the middle
annulus gear increases the speed and the power is transferred to front planetary gear.
The rear planetary gear set rotates in 1;1 ratio (same in 4th & 5th gears). However, the front
planetary gear set is not related to that, and the front sun gear increases its speed without load
(idling). -

1. OVERVIEW
This vehicle is equipped with WM6F1 M/T (Manual Transmission). This transmission is integrated with an
axle and designed to maximize the driving performance by optimizing the gear ratio according to the
engine torque.
WM6F1 M/T assembly

3190-01
1) Characteristics of WM6F1 M/T
Both Forward and Reverse gears use the helical gear and are made of high-strength material.
Drives the clutch with a concentric slave cylinder mounting bolt.
Shifting the transmission gears is performed through the remote control cable.
A pull type clutch is used for Reverse gear shifting.
Features triple/double/single synchronization. -
