C8AZ-19B546–A (Dana 80) or equivalent meeting Ford Specification
EST-M2C118–A for complete refill of limited slip 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 but do require a change. Refer to your Scheduled
Maintenance Guide for change intervals on Dana rear axles.

Ensure the correct automatic transmission fluid is used. Transmission
fluid requirements are indicated on the end of the dipstick. Check the
container to verify the fluid being added is of the correct type. Refer to
your Scheduled Maintenace 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
, MERCON V and MERCON SP are not
interchangeable. DO NOT mix MERCON
, MERCON V and
MERCON
SP. Use of dual usage fluids in an automatic
transmission application requiring MERCON
SP may cause
transmission damage. Use of a transmission fluid other than the
recommended fluid may cause transmission damage.
