PLANETARY GEARTRAIN

DESCRIPTION
The planetary geartrain is located between the
input clutch assembly and the rear of the transaxle
case. The planetary geartrain consists of two sun
gears, two planetary carriers, two annulus (ring)
gears, and one output shaft (Fig. 332).
OPERATION
The planetary geartrain 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.

SEAL - STUB SHAFT (LONG)

REMOVAL
If it has been diagnosed that the long stub shaft
seal is leaking, the following procedure can be used
to replace failed seal. This procedure will allow the
replacement of the seals without having to set back-
lash and measure differential bearing turning torque.
