6.1.5 The transmission controls (refer to hydraulic diagram)
The transmission is controlled by the direction and range solenoids. The solenoids are mounted on the left
side of the transmission case. When the selected direction and range solenoids are energised, oil under
pressure will flow through tubes and passages to the selected clutch shafts. Oil sealing rings are located on
the clutch shafts. These rings direct oil under pressure through a drilled passage way in the shaft to the
desired clutch.
