Examination
Check oil level and temperature (80-100°С), and engine coolant temperature (80-100°С).
Place blocks under the rear wheels.
With the parking brake fully applied and the brake pedal fully depressed, start the engine.
Set the gear selector lever to position D, fully depress the accelerator pedal and determine the engine speed at this point.
Control lever position
Attention: Hold the accelerator pedal for no more than eight seconds.
After each check, move the selector lever to position N and let the engine run at 1000 rpm until the temperature of the fluid in the gearbox reaches the operating temperature, after which the next check can be carried out,
Repeat the same test for selector lever position R.
Analysis of test results
If the engine speed during the test on the D and R ranges is greater than the maximum value (3000 rpm), then it says:
- low pressure in the main line;
- sliding brakes in first gear and reverse gear.
If the engine speed is greater than the nominal value only in the D range, then this indicates slipping of the downshift clutch.
If the engine speed is greater than the nominal value only in the R range, then this indicates slipping of the reverse clutch.
If the engine speed in the D and R ranges is less than the minimum nominal value, then this indicates:
- torque converter malfunctions;
- engine malfunction (insufficient power).
