Solenoids turn the flow of oil to the transmission clutches on and off. When a direction and gear are selected by the operator, the control module activates the appropriate solenoids. For movement of the machine, the activation of two solenoids are required. The first solenoid is activated for direction and the second is activated for the selected gear. See Table 1 for connections. See Table 2 for combinations.
