Automatic Transmission Third Gear Hold
(If Equipped)
If your vehicle is equipped with this feature, your range
-
selector has a "2 3" position. You can't shift up to the
next higher gear when the transmission is in this position
-
unless your engine governed speed is exceeded, such as
when going downhill.
This feature is useful for certain load and traffic
conditions. See the Allison Automatic Transmission
Operator's Manual in your vehicle for further information.
Manual Transmission
Using the Clutch
When you're starting to move the vehicle, it's important
to begin with the engine speed at idle. Then start to
engage the clutch and listen for an engine speed drop of
about 100 rpm. At this point, the clutch is engaging, so
you should increase the engine speed and fully engage
the clutch. It's important not to increase the engine
speed sooner or before the clutch begins its engagement.
If you do, you can cause damage to your vehicle.
Double-Clutching
You must use the "double
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.
5- and 6-Speed Transmissions
These transmissions have gears that automatically
synchronize when you shift up or down (except
FIRST (1) gear on the five
unsynchronized). Choose the gear which will maintain
the road speed you want while keeping the engine above
-
two thirds of the governed speed. When the engine
-
speed drops below two thirds of the governed speed,
shift into the next lower gear before your engine begins
to lug. When you shift down, be sure to double
if required.
