Center Housing Assembly
The center housing assembly is the main part of the transmission. Channels oil to various assemblies and houses
all major transmission assemblies. Contains drilled and tapped bosses on bottom for mounting transmission to
maintenance stand.
The main items in the left side of the transmission make up the range pack. The range pack is a group of clutch
assemblies and planetary gear assemblies that enable transmission speed and power output to be changed. The
range pack also enables the vehicle to move in forward or reverse direction. Refer for Figure 7 for an exploded
view of the major components in the left side of the center housing assembly.
