Tow/Haul Mode (Allison Transmission
®
or Hydra-Matic
®
6-Speed Automatic
Transmission)
Vehicles with an Allison or Hydra-Matic
®
6-speed
automatic transmission
®
have a tow/haul mode. The
tow/haul mode adjusts the transmission shift pattern to
reduce shift cycling, providing increased performance,
vehicle control, and transmission cooling when towing
or hauling heavy loads.
Turn the tow/haul mode on and off by pressing the
button, located on the end of the shift lever. When the
tow/haul is on, a light on the instrument panel cluster
will come on.
