meeting Ford specification EST-M2C118-A for complete refill of limited

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

your Scheduled Maintenance Guide to determine the correct service
interval.
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
