Fluid Change Intervals

Every 100,000 miles, the transmission fluid should be drained, the oil pan removed, the screen cleaned and fresh fluid added. For vehicles subjected to more severe use such as heavy city traffic, where temperatures reach90°F,or prolonged periods of idle or towing, this maintenance should be performed every 15,000 miles.
