T850 MANUAL TRANSAXLE
DESCRIPTION
The NV T850 5-speed transaxle (Fig. 1) is a con-
stant-mesh manual transaxle that is synchronized in
all gear ranges, including reverse.
The transaxle consists of three major sub-assem-
blies: the input shaft, intermediate shaft, and differ-ential assembly. The transaxle shift system consists
of a mechanical shift cover, rails, forks, and cables.
The unique design of this shift system provides a
higher mechanical advantage, resulting in less fric-
tion and lower shift cable loads for smoother, more
positive operation.
