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 and also in the Lubricant specifications section in this chapter. Note: Only one ATF fluid specification has been tested and approved for use with 6-speed-Premium Automatic Transmission fluid. Mercon fluids cannot be used in a automatic 6-speed without damage or voiding warranty. Use of a non-approved automatic transmission fluid may cause internal transaxle 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 a qualified technician. An overfill condition of transmission fluid may cause shift and/or engagement concerns and/or possible damage. Do not use supplemental transmission fluid additives, treatments or cleaning agents. The use of these materials may affect transmission operation and result in damage to internal transmission components.
