Notice:
If a two-wheel drive
vehicle or a four-wheel drive
vehicle with a single speed
automatic transfer case is towed
with the rear wheels on the
ground, the transmission could
be damaged. The repairs would
not be covered by the vehicle
warranty. Never tow the vehicle
with the rear wheels on the
ground.
Two-wheel-drive vehicles and
four-wheel drive vehicles with a
single speed automatic transfer
case should not be towed with the
rear wheels on the ground.
Two-wheel-drive transmissions have
no provisions for internal lubrication
while being towed. Four-wheel drive
vehicles with a single speed
automatic transfer case have no
neutral position and will spin the
transmission when the rear
wheels turn.
