Adjustment without using a tester
Remove the parts down to the oil filter in the same order as in the main line pressure adjustment procedure. Do not remove the control valve block.
Turn the adjusting screw on the bottom of the pilot valve block and adjust the reduced pressure to match the nominal pressure. Turning the adjusting screw clockwise decreases the reduced pressure, turning the adjusting screw counterclockwise increases it.
Note. When adjusting, the underpressure must reach an average value (425 kPa) from the range of nominal values.
Note. Rated value: 420±20 kPa.
Change in oil pressure with each turn of the adjusting screw: 22kPa.
Install the oil filter and oil pan in the same order as the main line pressure adjustment procedure.
Check the pressure in the hydraulic control system of the automatic transmission. Repeat pressure adjustment if necessary.
Adjustment using a tester
Using the ACTUATOR TEST mode (check of executive devices) tester force 50% cycle duty cycle (50% duty) pressure control solenoid valve (PCSV) and measure the pressure applied to the positive downshift brake at this time.
If the pressure supplied to the positive downshift brake (kickdown brake pressure), out of the nominal value range, adjust the pressure with the adjusting screw.
Rated value: 320±30 kPa.
Change in oil pressure with each turn of the adjusting screw: 30 kPa.
Check that after completing this adjustment, the underpressure value (reducing presure) corresponds to the range 370–490 kPa.
Attention! Adjustment should be made at oil temperature (ATF) in automatic transmission 70–80°С. If the adjustment is made when the oil temperature is too high (ATF) in an automatic transmission, the pressure in the main line will drop when the engine is idling, and as a result, correct adjustment will not be possible.
Replacing the wheel drive shaft seals
Disconnect the wheel drive shaft from the gearbox.
Pic. 3.81. wheel wire shaft seals
Using a flathead screwdriver, remove the seal (pic. 3.81).
Pic. 3.82. Pressing in the stuffing box
With a special tool (mandrel 09431-21200) install a new oil seal into the gearbox with light blows (pic. 3.82).
Apply automatic transmission oil (ATF) on the working edge of the gland.
Replacing the speedometer cable
Pic. 3.83. Speedometer Cable Adapter
Correctly install the adapter in the instrument cluster and tie a new speedometer cable to it (pic. 3.83).
Install the rubber bush so that the cable and the protruding part of the bush are horizontal.
Attention! The speedometer drive cable should be routed so that the bending radius of the cable is 150 mm or more.
Pic. 3.84. Installing the speedometer cable
On the gearbox side, insert the tip of the speedometer cable into the gearbox and securely tighten the fastening nut (pic. 3.84).
Attention! If the speedometer cable is connected incorrectly or loosely, the speedometer reading will be incorrect and abnormal noise will occur. Make sure the speedometer cable is connected correctly.
