7. 9 TRANSMISSION OPERATION
The transmission is hydraulically driven and power shifted. Shifting method is as follows:
a) The transmission is divided into high gear and low gear ranges. The low gear range is
in manual shifting mode and the vehicle is started in the 1
st
b) When shifting, the transmission shift lever must be shifted in position;
gear position. The high
gear range is in automatic shifting mode and the vehicle can be started at any gear
position;
c) When there is abnormal noise in the transmission or it is difficult to operate the
steering wheel, bring the vehicle to a standstill and rectify it at once according to the
Transmission Maintenance and Service Manual;
d) The transmission shift lever should be moved to “N” position when parking the vehicle;
e) Check the transmission oil level when the vehicle is stopped and the engine is running
at idle speed.
The oil temperature of transmission should be between 180 – 200
℉ (82 – 93℃) for
normal operation.
When the oil temperature exceeds 250℉ (121.1℃), stop the vehicle immediately to
cool down: move the transmission shift lever to “N” position and keep the engine
RPM within 1000 – 1200 rpm, then the oil temperature will decrease immediately.
It is forbidden to turn off the engine when the transmission gear oil temperature is
excessively high.
It is forbidden to drive the vehicle when the transmission oil pressure is lower than
240 psi. Excessively low oil pressure may result in clutch skid, thus shorten the
service life of clutch.
During driving, do not shift between forward gear and reverse gear. It is forbidden to
make the vehicle glide forward by its inertia when the transmission is moved to the
neutral position.
