2002 FORD SUPER DUTY fuel

Traction-Lok axles. Ford design rear axles contain a synthetic lubricant
that does not require changing unless the axle has been submerged in
water. Dana rear axles also contain a synthetic lubricant butdorequire a
change. Refer to your “Service Guide” for change intervals on Dana rear
axles.
2Ensure the correct automatic transmission fluid is used. Transmission
fluid requirements are indicated on the dipstick or on the dipstick
handle. Check the container to verify the fluid being added is of the
correct type. Refer to your scheduled maintenance guide to determine
the correct service interval.
Some transmission fluids may be labeled as dual usage, such as
MERCON
and MERCON
V. These dual usage fluids are not to be used
in an automatic transmission that requires use of the MERCON
type
fluid. However, these dual usage fluids may be used in transmissions that
require the MERCON
V type fluid.
MERCON
and MERCON
V type fluids are not interchangeable.
DO NOT mix MERCON
and MERCON
V. Use of a transmission
fluid that indicates dual usage (MERCON
and MERCON
V) in
an automatic transmission application requiring MERCON
may
cause transmission damage. Use of any fluid other than the
recommended fluid may cause transmission damage.
