TM 5-3825-226-24 CLUTCH NO. OPERATION No.1 Forward Direction (fourth speed) No. 2 Reverse Direction No. 3 Forward Direction No. 4 Third Speed No. 5 Second and Fourth Speeds No. 6 First Speed Most all the components inside the planetary transmission turn when the controls are in each FORWARD or REVERSE speed. Only these components that have been made dark in the illustrations that follow are used in the flow of power through the transmission. FIRST SPEED FORWARD POWER FLOW THROUGH TRANSMISSION IN FIRST SPEED FORWARD (No. 3 and No. 6 Clutches Engaged.) The No. 3 clutch ring gear is held stationary. This causes the No. 3, No. 4 and No. 5 carriers and No. 6 clutch to turn. Since the No. 6 clutch is engaged, torque is sent to the No. 6 clutch gear and output shaft. SECOND SPEED FORWARD The No. 3 clutch ring gear is held stationary. This causes the No. 3, No. 4 and No. 5 carriers to rotate. The No. 5 clutch ring gear is held stationary by the engaged No. 5 clutch. The No. 5 planet gears turn around the inside of the No. 5 clutch ring gear driving the No. 5 sun gear which in turn drives the No. 6 clutch gear and output shaft. POWER FLOW THROUGH TRANSMISSION IN SECOND SPEED FORWARD (No. 3 and No. 5 Clutches Engaged.) THIRD SPEED FORWARD POWER FLOW THROUGH TRANSMISSION IN THIRD SPEED FORWARD (No. 3 and No. 4 Clutches Engaged.) The No. 3 clutch ring gear is held stationary by the No. 3 clutch. The No. 4 clutch ring gear is held stationary by the No. 4 clutch. The No. 3 sun gear drives the No. 3 planet gears which turn around the inside of the No. 3 clutch ring gear to rotate the No. 3 carrier. The No. 4 planet gears are driven around the inside of the stationary No. 4 clutch ring gear and drive the No. 4 sun gear, No. 6 clutch gear and output shaft. FOURTH SPEED FORWARD The No. 1 clutch holds the No. 2 carrier to the input shaft which causes the No. 2 and No. 3 ring gears, carriers, and carrier ring gears to turn at transmission input speed. The rotation of the No. 3 and No. 4 carriers send torque to the No. 4 ring gear and sun gear. When the No. 5 ring gear is held stationary by the No. 5 clutch, torque is sent by the No. 4 and No. 5 sun gears to the output shaft. 2-84
