Fluid Change Intervals
If the transmission is subjected to severe service such as: use in heavy city traffic when the outside temperature regularly reaches 90°F, use in very hilly or mountainous areas, commercial use such as taxi or delivery service, the fluid should be changed every 15,000 miles. Otherwise, change the fluid every 100,000 miles, using Dexron II or equivalent automatic transmission fluid.
