Planetary Geartrain
PLANETARY GEAR-TRAINDESCRIPTION
The planetary gear-train is located between the input clutch assembly and the rear of the transmission case. The planetary gear-train consists of two sun gears, two planetary carriers, two annulus (ring) gears, and one output shaft (Fig. 251).
OPERATION
The planetary gear-train utilizes two planetary gear sets that connect the transmission input shaft to the output shaft. Input and holding clutches drive or lock different planetary members to change output ratio or direction.
