Pressure check трансмиссионной liquids (F4A42)

Pressure check трансмиссионной liquids is carried out to define a condition of hydraulic components and whether there are leaks.

PERFORMANCE ORDER

Start up the engine before warming up of a transmission to temperature 80–100C. Lift the forward party of the car so that driving wheels could rotate freely.

Connect a special manometre with an adapter to each union of check of pressure.

трансмиссионной

If pressure does not correspond to demanded values, check up and repair transmission elements.
