Transmission's Proper Use and Care
1. Transmission's proper operation
1.1 Shift the gear gently, not excessively.
1.2 Do not start with high speed.
1.3 To avoid premature abrasion of the gear shift fork, do not rest your hand on the \
gear lever while driving.
2. Model number of the lubricant to be used:
GL-4 80W-90 (For China domestic model)
GL-4 75W-90 (For alpine region model)
GL-5 140 (For high-temperature region model)
Caution: Please only use the lubricant with model numbers specified by t\
he Great Wall Motor Co., Ltd.
Do not mix lubricants with different model numbers. Only fill with clean lubricant.
3. Areas of importance for new vehicle usage:
3.1 Before using a new vehicle, be sure to check the transmission and all exposed connectors and fastening
pieces, so as to avoid failure due to faulty installation or loose conne\
ctions.
3.2 Since the new vehicle is still in the run-in period, the transmission's lubricant should be replaced after 5000 km
distance.
4. Transmission three-level maintenance:
4.1 Transmission level-one maintenance: During the first level of maintenance, the liquid level of the lubricant
should be checked to ensure that it is up to the oil-filling mouth. Add more if insufficient. Excessive low
oil level can lead to ineffective lubrication, as well as burning of the bearings and gears. Excessive high oil
level, however, can overheat the transmission or cause oil to leak. In addition, during the first level of main-
tenance, the breather plug should be checked and cleaned. If the breather plug is clogged, internal pressure
will build up and oil will leak from the transmission.
4.2 Transmission level-two maintenance: The transmission's lubricant should be replaced the first time that the
vehicle undergoes the second level of maintenance. Clean the transmission with kerosene. The quality of the
lubricant should be inspected during the future second level of maintenance practises. The lubricant should
be replaced if diluted, gummy, or dirty.
4.3 Transmission level-three maintenance: During the third level of maintenance, it should be removed for in-
spection, cleaning, and oil changing.

Areas of Importance
Removal
During removal, all components should be gently handled to avoid knocking, especially the joint surface.
All components should be placed in the proper order to avoid misplacing \
and mistaking.
Installation
1. Clean all parts before installation (except rubber pieces and gaskets)\
.
2. All oil seals, shaft retainers, and elastic pins should not be reused.
3. All rubbing surfaces should be coated with lubricant, and the lips of all oil seals should be coated with
grease.
4. During installation of the bearings, do not use any kind of rolling element to transmit pressure, and
make sure not to tilt it.
5. During the installation of synchronizer components, the two sides of the spring piston's openings
should alternate.
6. When the transmission is operating under normal working conditions, there should be no lubricant
leakage from any of the parts.
Transportation and storage
1. When transporting a transmission, make sure the conditions are dustproof and rainproof, as well as
take proper care not to damage it due to jolting, shaking, removal, or i\
nstallation.
2. Transmission assembly should be stored in a ventilated, dustproof, and dr\
y place.
3. Users with special transportation or storage requirements should have another discussion to reach an
agreement on this matter in the supply contract.

Drive shaft removal
1. First use a M32 sleeve, ratchet wrench, and extension
bar, to remove front drive shaft nut LH. Then, according
t o t h e w h e e l a n d f r o n t s u s p e n s i o n d i s a s s e m b l y
specifications, remove the Front suspension system
LH and wheel.
2. Then use a pry bar to forcefully pry the connection
between the differential and the drive shaft until the
drive shaft obviously moves towards the outside. Do
not damage the drive shaft's dust cover.

Drive shaft installation
1. Insert the drive shaft.
First, align the inner end of the drive shaft and differential
spline. Keep the drive shaft axes and the differential axes
bases uniform, then hammer towards the direction of the
differential drive shaft's outer end until a clear and sharp
clicking sound is heard. Here, the drive shaft and the
transmission should have a clearance of about 1 mm.
2. According to the front suspension and wheel assembly
installation specifications, properly install the front
shock absorber with coil spring assembly LH and
wheel.
3. Use an M32 sleeve, ratchet wrench, and extension bar
to tighten front drive shaft nut LH.

Immobilizer System
Immobilizer system composition
This vehicle's engine immobilizer system consists of a theft deterrent ECU assembly, a theft deterrent coil as-
sembly, and two theft deterrent converter assemblies. The theft deterrent coil assembly is put on the head of
ignition lock cylinder, with the other end connected to the theft deterrent ECU assembly. The two theft deterrent
converter assemblies are separately installed inside the plastic handles\
of the two keys.
1. Position diagram
All the components of immobilizer system are assembled on the overall vehicle except for the theft deterrent
converter assemblies inside the keys. They achieve communication functions via the wire harness connections.
The following figure shows the position of each component in the overall\
vehicle.

Ignition lock key
Theft deterrent coil
Steering column
2. Theft deterrent controller
The theft deterrent controller assembly mainly consists of a microprocessor and peripheral components. It com-
municates with the password transmitter assembly and engine ECU. The theft deterrent controller assembly
communicates with the engine ECU via the W wire, while communicating with the theft deterrent transponder
assembly via radio frequency. The theft deterrent controller connects with the scanner via the K wire. Through
the scanner, it can initiate matching, state controlling, and malfunction diagnosti\
c on the immobilizer system.
3. Theft deterrent coil
The theft deterrent coil assembly is installed on the ignition lock cylinder, the other end of wire harness
plug is connected to the theft deterrent controller assembly. The theft deterrent coil assembly can generate
an electromagnetic field to achieve communication between the theft deterrent controller assembly and the
password transmitter assembly.
4. Transponder
The theft deterrent transponder is installed inside the key handle. It has no power supply, maintains a small size,
and long use life. It acquires electric energy and transmission signals using the stimulation of the electromagnetic
field generated by the theft deterrent coil, so as to communicate with t\
he theft deterrent controller assembly.
