Test in garage

This test checks the general work of an automatic transmission and the engine by means of measurement of bench speed in situation of "D" and “R”. At carrying out this test be convinced that liquid of an automatic transmission has normal working temperature, and its level is between marks "Full" and "Low".

  • Do not hold the engine on bench speed continuously more than 5 seconds as liquid can heat up very strongly.
  • Having executed bench test, let's to the engine work idling not less than 30 seconds before the following bench test.

 PERFORMANCE ORDER

  1. Put the car on the parking brake and block wheels.
  1. Establish a tachometer.
  2. Start the engine, having switched the lever of transfer to the situation "R".
  3. Press a brake pedal to the full.
  4. Switch the lever of transfer to situation "D" and press a "gas" pedal to the full, looking thus at a tachometer. When speed of the engine (rpm) becomes a constant (bench speed), quickly remember its value.
  5. Release a "gas" pedal right after check of bench speed.
  6. Similarly check bench speed in the situation "R".
  7. Bench speed should be within the following borders:
  • Bench speed:
    • 2,100-2,400 «í./minute for the G16 engine
    • 2,300-2,600 «í./minute for the J20 engine

Results of check

Possible reason

Level is lower than the standard

* Inadequate effective power of the engine

* Faulty hydrotransformer

Level is higher standard in situation "D"

* coupling of raising transfer Slides off

* forward coupling Slides off

* the Faulty coupling of a free wheeling of raising transfer

* Faulty coupling free course No. 2

* Low linear pressure

Level is higher standard in the situation "R"

* direct coupling slides off

* the backing brake Slides off

* Low pressure of liquid

* coupling of raising transfer Slides off

* the Faulty coupling of a free wheeling of raising transfer
