Section I.
DESCRIPTION AND DATA
This chapter covers maintenance procedures for the transmission, as well as principles of operation.

a. General. The transmission has four forward and four reverse speeds, with speed and direction
controlled by hydraulic operated clutches. Engine torque is coupled to the transmission through the torque
converter (1).
b. Torque Converter. The torque converter (1) couples engine torque to the transmission input shaft. It is
basically a fluid drive, which has no mechanical connection through it. This feature not only eliminates nearly
all wear, but also provides a smooth and almost shock-free drive which prevents engine stalling and lugging.
Under light loads, engine speed is transmitted at almost a 1:1 ratio through the torque converter. As loads
increase, however, the torque converter inherently multiplies engine torque. The need to manually shift
transmission gears is therefore greatly reduced, but not totally eliminated.
c. Clutches. The clutches are hydraulically applied and spring released. Using hydraulic power to control
clutch application permits automatic compensation for clutch wear; therefore, there is no need for clutch
adjustment. Each clutch contains a number of paper graphitic friction plates and polished steel reaction
plates. Clutch actuation determines speed and direction of rotation of output shafts (2 and 3), which transmit
power to the respective axle differentials.
