Caution
If a two-wheel-drive vehicle 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.
To dolly tow a two-wheel-drive
vehicle or a four-wheel drive vehicle
with a single speed automatic
transfer case, the vehicle must be
towed with the rear wheels on the
dolly. See Rear Towing (Rear
Wheels Off the Ground) later in this
section.
