Additional Notes
- The Ford Aerostar (USA) transfer case fluid capacity is listed at 4.3 liters for both the 3.0 V6 and 4.0 V6 engine configurations across the 1996-1997 model years.
- A 4.3-liter transfer case fill volume is a relatively substantial capacity, consistent with a full-size transfer box unit rather than a smaller auxiliary unit, reflecting the total fluid volume needed to properly lubricate all internal gears and bearings.
- The 12-month check interval applies under normal use conditions for both engine variants, meaning the fluid level in the transfer case is to be inspected on an annual basis rather than at a mileage-based threshold.
- The specifications carry no distinction between the 3.0 V6 and 4.0 V6 in terms of either capacity or service interval, with both sharing the identical 4.3-liter fill and 12-month check schedule under normal use.
