MERCON V. Refer to the scheduled maintenance information to
determine the correct service interval.

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.

Rear axles are considered lubricated for life when the vehicle is used for

Service refill capacities are determined by filling the rear axle 1/4 inch
