Check of pressure of transmission liquid (F4A42)

Check of pressure of transmission liquid is carried out to define a condition of hydraulic components and whether there are leaks.

 PERFORMANCE ORDER

    Start up the engine before transmission warming up to temperature 80–100°C. Lift the forward party of the car so that driving wheels could rotate freely.
    Connect a special manometer with an adapter to each union of check of pressure.
    Measure pressure of transmission liquid at various positions of the lever of the selector and frequency of rotation of a cranked shaft of the engine given in the table.
    If pressure does not correspond to demanded values, check and repair transmission elements.
