Add 236 ml (8 oz.) of Additive Friction Modifier XL-3 (10.5 inch) or

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 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

, MERCONV and MERCONSP are not

interchangeable. DO NOT mix MERCON

, MERCONV 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.
