Cooling and lubrication.
In addition to transmitting torque and motion, the
continual movement of oil through the converter assembly
provides lubrication and cooling. (page 12, para 7)
The first, second, and fourth clutches are used to provide
a forward and reverse range.
The only time the third

The output pump check valve opens and allows
output pump to feed the primary hydraulic circuit.
This normally closed check valve provides an interface
between the main pump and the output pump.
If the main
pump fails for any reason, this check valve reacts by
opening and allowing the output pump to provide pressure
and flow to the main hydraulic circuit. (page 27, para 2)
Direction of rotation of the hydrostatic pump.
The function of the supercharge check valves is to provide
oil to the hydrostatic pump at all time. The direction of
rotation of the hydrostatic pump determines which port will
be pressure and return.
Since the rotation of the pump
determines which one of them will be open to provide oil to
the pump continuously. (page 59, para 2)
