based on cooler size and if equipped with an in-tank cooler. The amount
of transmission fluid and fluid level should be set by the indication on
the dipstick’s normal operating range.
3Service refill capacity for the manual transmission is determined by
filling the transmission to the bottom of the filler hole with the vehicle
on a level surface.

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