This will improve performance and reduce the potential
for transmission overheating or failure due to excessive
shifting. When operating in “TOW HAUL” mode, 5th
gear (if equipped) is disabled and 2-3 and 3-4 shift
patterns are modified. Shifts into Overdrive (4th gear) are
allowed during steady cruise (for improved fuel
economy) and automatic closed-throttle downshifts to
3rd gear are performed (for improved braking) when
driving conditions warrant. Pressing the “TOW HAUL
O/D OFF” button a second time to select O/D OFF will
disable 4th and 5th gear completely, which should elimi-
nate any excessive transmission shifting.
The “TOW HAUL” or “O/D OFF” light will illuminate in
the instrument cluster to indicate when the switch has
been activated. Pressing the switch a third time restores
normal operation. If the “TOW HAUL” or “O/D OFF”
modes are desired, the button must be pressed each time
the engine is started.
