Selection of drive mode
The selection of drive mode includes a mode selection switch and indicator lamp. The drive mode selection switch is located
on the operating panel. It can provide the different mode selection according to the different type of car.
It has the optimal fuel economy when select the “normal” mode. At this time, the indicator lamp is not light. When select the
“dynamic” mode, the car will have the maximum dynamic performance and the “dynamic” mode indicator lamp is light. When select
the “snowland” mode, it will realize the starting of “2
nd-Gear”, the “snowland” mode indicator lamp is light, meanwhile the
“dynamic” mode indicator lamp will be closed. When select the manual mode, press down the “snowland” switch firstly, the
“manual” light will be light when the gear is in 3, 2, 1. When in manual mode, 1-2, 2-3, 3-4, 3-2, 2-1, 1-3, 3-1 is shifted by driver
manually and can not be shifted automatically. It can be used in car-racing etc. for the special mode of each model of car refers to
operation manual of user.

7 It must place the transmission in the P-Gear or N-Gear when start the engine.
8 It must place the transmission in P-Gear during the parking.
9 It must place the transmission in N-Gear when trail the car.
10 It must be powered off when remove the transmission.
11 It must be powered off when install the transmission.
The transmission processes the communication and calculation with the engine electronic control computer by the precision
central on-line computer. It not only save the fuel, but also provide the maximum mode function, including field, winter and
manual selection. It provides the two conditions, manual and electric for the fast race of racing player. It has racing capacity wh i ch

12. Primary regulating valve
Primary regulating valve (PRV) (refer to Figure 3.18) can regulate the line pressure of transmission (or pump output
pressure). The valve can give the high or low line pressure according to the on/off status of S6. When S6 is in on or off status,
the pressure S6 is applied on PRV, move it and has the action of spring force. Open the line pressure loop to turn on the inlet
of pump to reduce the line pressure. Generally, the line pressure is small when the throttle position is opened lightly and in
patrol status. It will cause the closing of S6 when the opening degree of throttle position is large and because the high line
pressure valve
For all shifting pressures are controlled by output of separation brake belt , clutch regulating valve and S5, so all step control
of line pressure has not affect on effect of shifting sensing.
By the oil inlet of torque converter, PRV also adjust the oil supply of hydraulic torque converter. The level effect of PRV
should ensure the priority of valve, i.e. it can keep the line pressure in low engine speed condition. When the speed of engine
is increased and the pump supplies excess oil, the PRV acts to open the torque converter oil inlet cover to increase the pressure
of torque converter. If the oil amount is beyond the requirement of transmission, PRV will act further to allow the oil return
to the suction inlet.
Figure 3.18 Primary regulating valve
Figure 3.19 Torque converter on/off regulating valve
The torque converter regulating valve (refer to Figure 3.19) adjusts the pressure applied on torque converter clutch oil.
According to the signal pressure form loop S5, adjust the oil flow status from line pressure loop in valve. With the change of
pressure signal of loop S5, the engagement and disengagement of torque converter clutch can be finished by electric control.

3. Oil filling of service after sales
Set the liquid level position correctly; the procedure is shown as follows:
a. Shut down the engine; place the gear-position in the P-Gear.
b . Lift the vehicle (or place it above the trench).
c. Clean the around of plug before remove it. Remove the oil plug and check the O-ring for damage, finally connect the oil filling
pump to the oil filling hole.
d. Lower the vehicle and oil filling pump to the ground; fill with the transmission fluid partially. The general oil filling amount
is shown as follows:
If in the status of transmission hydraulic torque converter is empty: 8.0 L
If in the status of transmission hydraulic torque converter is full: 3.8 L
e. When start the vehicle in P-Gear, rotate the engine in idle speed. Step down the foot brake, pull the shifting lever in each gear-
position in circulation and add the transmission fluid until the action of each gear-position can be sensed.
f. Then fill with 0.5L transmission fluid (ATF) additionally.
g. Shut off the engine, lift the vehicle; take off the pump and replace the plug. Ensure the plug is tightened according to the
specification.
h. Then pull the vehicle throttle position for slight opening to make the vehicle runs for 3.5
4.5km; the rotary speed of engine
is no more than 2500r/min; then the transmission fluid temperature will in the scope of 50
60.
i. The engine is in idle-speed; pull the hand brake to make the shifting lever circuits in each gear-position horizontal status.
k. Remove the filling plug 3 minutes after the engine is shut off, but must be no more than1 hour. At this time, the correct
level position should be in the bottom of oil filling hole. If does not reach the liquid level position, then fill with few
transmission fluid (ATF) to meet the requirement.
l. Reinsert the transmission fluid plug, remove the residual transmission fluid around the vehicle and transmission; tighten the
plug to the specified torque.
4. Replace the ATF
Please notice that the color of TQ95 automatic transmission oil will be faded in the normal operation of transmission; it will be
turn into the deep brown or even in black. It will not affect the performance of ATF. It means that the fading of transmission
fluid not always means to replace the transmission fluid.
If the transmission temperature is raised, the ATF will be burnt. In this condition, ATF will change into black and with special
sulfur smell. The smell of the ATF means the oil is burnt.
If the ATF is burnt, it will cause the damage of transmission (the clutch assembly is damaged at least).At this time, it should
disassembly the transmission and process the necessary detection.
Electronic calibration
1. Idle-speed calibration
The idle-speed calibration is introduced in detail in the vehicle factory manual.
2 Calibration of position of throttle position

If the throttle position information stored in TCU is lost or not in application scope. It can be reestablished according to the
following program as the diagnosis error information.
a. Check whether the engine idle speed is in required range.
b. In the status of shutting off of air-condition, make the engine is in “D” –Gear for 60s,then the reference point with opening
degree of 0
of throttle position is reset in TCU.
Shut off the engine; switch on the ignition device, step the accelerator pedal to bottom for 60s, then the reference point with opening
degree of 100
of throttle position is reset in TCU.
