Examination
1. Check the automatic transmission oil level.
2. 2WD models: Apply the parking brake and chock the rear wheels. Jack up the front wheels and support the vehicle so that the front wheels can turn.
4WD models: Jack up all 4 wheels and support the vehicle on stands so that all wheels can turn.
3. Start the engine and warm it up until the radiator fan starts to run for the second time.
4. Turn off the engine and connect the speed sensor (tachometer).
5. Install a set of pressure gauges in each inspection hole.

6. Start the engine, set the selector lever to position N or P, bring the engine speed to 2000/min and measure the pressure in the line.
If the selector lever is in a position other than N or P during measurement, the test result will not be reliable.
7. Check the pressure in the couplings, see table.
1st gear clutch pressure
Set the selector lever to range 2, press the Low Hold switch and engage range L. Keeping the engine speed at 2000/min, measure the pressure in the 1st gear clutch.
2nd gear clutch pressure
Press the Low Hold switch and switch off the L range. Set the selector lever to range 2. Keeping the engine speed at 2000/min, measure the pressure in the 2nd gear clutch.
Pressure in 3rd and 4th gear clutches
- (1) Set the selector lever to position P, depress the brake pedal and move the lever to position D.
- (2) Release the brake pedal (1st gear).
- (3) Press the accelerator pedal, bring the engine speed to 2500/min. (shifts from 1st to 2nd gear).
- (4) Make sure that the shift has occurred and after 5 seconds release the accelerator pedal (engine speed in 2nd gear drops to 1000/min.).
- (5) Slowly press the accelerator pedal for 5 seconds, bringing the engine speed to 2000/min. (shifts from 2nd to 3rd and from 3rd to 4th gear).
- (6) Measure the pressure in the 3rd and 4th gear clutches.
8. After completing the check, install new sealing washers and tighten the bolts to 18 N·m (1.8 kg·m).
