The vehicle manufacturers may choose different types of shift selectors for their
equipment. Different transmission models may also require different designations on
the shift selectors.
Typical Shift Selector Labeling
These are some of the typical shift selectors you may find in Allison-equipped
vehicles. The range selector in your vehicle may vary from these or may have
1
(First Range) at the top and
R
(Reverse) at the bottom. Some models may have
a
P
(Park) position.
The best performance will be obtained by using the correct range for each driving
condition. The following table illustrates shift patterns for the various models and
indicates the page that explains the shift pattern for your vehicle.
