Connect a pressure gauge to the outlet fitting of the pressure regulator.
Start the engine.
Set the selector lever to position «D» and determine the value of the control pressure on the move at a speed of 30, 55 and 85 km / h.
If the obtained values do not correspond to the nominal (see subsection «Detailed Specifications»), check that there is no oil leakage in the working pressure and control pressure hydraulic circuits, and check the operation of the pressure regulator.
