3. FUNCTION TEST

When the transmission has been completely assembled
and filled up with transmission fluid, it would be convenient
to make a function test.
This test can be carried out on a bench test rig, or in a boat.
If no fluid cooler can be connected, a hydraulic hose must
be connected between the inlet and outlet of the hydraulic
pump.
