3.3.2 Description and Operation
3.3.2.1 Transmission System Operation

Warning!

During the diagnostic and repair process, we must
strictly follow the safety operating standards, in order to
prevent personnel injury and damage to the vehicle.
Refer to "Vehicle lifting Warning" and " Road Test
Warning" in "Warnings and Notices".

During the transmission service, it is necessary to prevent dust
entering the system. we must use the transmission service
special tools, not only we can improve the service efficiency
and quality, but also prevent unnecessary vehicle damage.
The manual transmission is a regular full-mesh five-speed
transmission synchronizer.

Shift control is shown as in the graphic:

Shift Control Assembly

Shift control assembly is to select the gear through the fork
movement. Self-locking bolt is used to prevent the gear
jumping out. Between the 5th/reverse gear fork and the 1st/2nd

gear fork, and between the 5th/reverse gear fork and the 3rd/
4th gear fork, there are interlock pin to prevent engaging two
gears at the same time, so as to ensure transmission work
properly.

Gear

Forward Gear

Forward gear disengaged by a group of shift fork to control the
sliding lock ring synchronizer.

Reverse Gear

Reverse gear is not synchronized, using a sliding idler wheel.
When the reverse gear is engaged, sliding idler pulley will be
meshing with the input shaft and main shaft reverse gear
reverse output gear at the same time, to transmit the input
torque to the main shaft output, and so that the main shaft
rotation is opposite to that when the forward gears are
engaged, thus reversing the vehicle.
