(2) High Range.
When the transfer is shifted into
high range, the synchronizer assembly is moved
rearward on the input shaft to engage the input-shaft
high-speed gear, which is in mesh with the
countershaft high-speed gear. Because the high-speed
gear is keyed to the countershaft, power flow is
through the countershaft gears to the rear (and front,
if lockup assembly is engaged) output shafts and
gears.
(4) Neutral.
A neutral position is provided to
allow operation of the gear train when no motion of
the vehicle is desired.
