TOWING OR PUSHING
CAUTION: Failure to lift the driving wheels off the road, disconnect
the driveline, or remove the axle shafts before pushing or towing can
cause serious transmission damage.
The engine cannot be started by pushing or towing. Before pushing or towing a
vehicle do one of the following:
•
Disconnect the driveline.
•
Lift the drive wheels off the road.
• Remove the axle shafts from the drive wheels.
An auxiliary air supply will usually be required to actuate the vehicle brake
system.
When the axle shafts are removed, be sure to cover the wheel openings to prevent
loss of lubricant and entry of dust and dirt.
PRIMARY/SECONDARY SHIFT SCHEDULES
The points at which shifts occur depend upon predetermined speeds and other
operating conditions. A transmission “shift calibration” includes several sets of
shift points which may be used according to current or anticipated operating
conditions. Some shift schedules may be inhibited as a result of operating
conditions, such as engine or transmission
fl uid temperature. Shift schedules may
be changed using the MODE button (some applications may use a dash-mounted
switch)—which is typically associated with a change in anticipated vehicle
operation.
The TCM includes the capacity for two separate and distinct shift calibrations
(customer-selectable), one for use in “Primary Mode” of operation and one in
“Secondary Mode.”
•
Primary —This shift schedule is typically used for all normal vehicle
operations.
• Secondary —This is an alternate shift schedule that the TCM uses upon
request. Not all vehicles will be equipped with a secondary shift schedule.
The request can be interlocked with a vehicle component, or be
operator-controlled using the
MODE button.
Your vehicle may have a dash-mounted light that illuminates when the secondary
mode is active.
