Maintenance and Specifications Adjusting automatic transmission fluid levels Before adding any fluid, make sure the correct type is used. The type of fluid used is normally indicated on the dipstick. Refer to Maintenance product specifications and capacities in this chapter. Use of a non-approved automatic transmission fluid may cause internal transmission component damage. If necessary, add fluid in 1/2 pint (250 ml) increments through the filler tube until the level is correct. If an overfill occurs, excess fluid should be removed by an authorized dealer.
