Transmissions
If your vehicle has one of these non-synchronized
transmissions, it is naturally somewhat
complicated.
The following are driving tips:
•
Always choose an initial starting gear suitable
for the load and terrain.
•
Always use double-clutching procedures when
shifting.
•
Never move the range shift lever to the
LO speed gear position after HI range
preselection, or anytime the transmission is in
the HI range.
•
Never move the range knob or lever with the
shift lever in NEUTRAL while the vehicle is
moving.
•
Never make a range shift while moving in
REVERSE (R).
Double-Clutching
You must use the double-clutching method when
you shift an unsynchronized gear set. Disengage
the clutch, shift to neutral and engage the
clutch. When upshifting, slow the engine until the
engine rpm and road speed match. When
downshifting, accelerate the engine until the
engine rpm and road speed match. Then quickly
disengage the clutch and move the shift lever
to the next gear position and engage the clutch.
