SERVICE INTERVALS

Check fluid level at every engine oil change. Fluid, filter changes and band adjustments are not required under normal operation. Under heavy duty (severe service), change fluid every 30 months or 30,000 miles. Adjust bands when fluid is changed.

CHECKING FLUID LEVEL

  1. With transmission at normal operating temperature, place vehicle on level ground. Apply parking brake, and run engine at curb idle. Shift selector through all positions, ending in Park.
  2. With transmission at normal operating temperature, fluid level should be between "ADD" and "DON'T ADD" or "MAX" marks on dipstick. If transmission is at room temperature, fluid level should be between middle and top holes on dipstick.
  3. If fluid level is correct at room temperature, it will be between "ADD" and "DON'T ADD" or "MAX" marks on dipstick when normal operating temperature is reached. Do not overfill. Check condition of fluid for contamination or burned smell. Fully reseat dipstick.

The C-5 and AOT transmissions use Motorcraft Automatic Transmission Fluid Type H (or equivalent meeting Ford specification ESP-M2C166-H). A4LD transmissions require Dexron II transmission fluid.

FLUID CAPACITY

Note. Transmission and converter assembly capacities given below are approximate, and correct fluid level should be determined by mark on dipstick, rather than by amount added.
