Fluid and filter changes or band adjustments are not required for average passenger car use. Severe usage such as police, taxi, trailer towing or prolonged operation in city traffic, requires that fluid and filter be changed and bands adjusted every 24,000 miles on Jeep models, and every 15,000 miles for Chrysler Motors vehicles. Consult owners' manual for specific mileage. Whenever the factory fill fluid is changed, only fluids of the type labeled DEXRON II should be used.
