Fluid Change Intervals

Check fluid at regular intervals. Noticing a change in color, odor or fluid level can serve as a warning of possible transmission problems.
To check fluid level, bring fluid to operating temperature of 200°F. With vehicle on a level surface, engine idling in park and parking brake applied, the level on the dipstick should be at the Full mark. To bring the fluid level from the Add mark to the Full mark requires one pint of fluid. If additional fluid is required, use only Dexron II or Dexron IIE automatic transmission fluid. When adding fluid, do not overfill, as foaming and loss of fluid through the vent may occur as the fluid heats up. Also, If fluid level is too low, complete loss of drive may occur especially when cold, Which can cause transmission failure.
Every 100,000 miles, the oil should be drained, the pan removed, the screen should be cleaned or replaced if applicable, and fresh fluid added. For vehicles subjected to more severe use such as heavy city traffic especially in hot weather, prolonged periods of idling or use as a tow vehicle, this maintenance should be performed every 15,000 miles.
