Automatic Transmission Operation
If your vehicle has an automatic transmission,
it features an electronic shift position indicator
within the instrument panel cluster. This display
must be powered anytime the shift lever is moved
out of PARK (P). See
Fuses and Circuit Breakers
on page 598
.
There are several different positions for your shift
lever.
See “Range Selection Mode” later in this section.
PARK (P):
This position locks your rear wheels.
It is the best position to use when you start
your engine because your vehicle cannot move
easily. If your vehicle has the Allison
Transmission
®
, with the Power Take-Off (PTO),
use PARK (P) when starting. The Allison
Transmission
®
has a park pawl that is designed to
hold the weight of commercial medium duty
trucks. Therefore, the Allison Transmission
®
uses
larger parts than other automatic transmissions.
These larger parts may sometimes make a
clunking noise when the selector lever is moved
from DRIVE (D) or REVERSE (R) to PARK (P).
This is normal and there is no damage occurring
during these shifts. When parked on a hill,
especially with a heavy load, you may notice an
increase in the effort to shift out of Park. See
Torque Lock (Automatic Transmission) under
Shifting Into Park (P) (Automatic Transmission) on
page 171
for more information.
