Maintenance and Specifications Checking automatic transmission fluid at cool temperature (59°F-77°F [15°C-25°C]) If a fluid check is necessary at a low fluid temperature (59°F-77°F [15°C-25°C]), perform the check using the cold range on the dipstick. However, the fluid must be re-checked at the proper fluid temperature. Low fluid level Do not drive the vehicle if the fluid level does not show at all on the dipstick. Driving the vehicle with less than the recommended fluid level may result in transmission failure. An under fill condition of transmission fluid may cause shift and/or engagement concerns and/or possible damage to the transmission. High fluid level Fluid levels above the normal operating range may result in transmission failure. An overfill condition of transmission fluid may cause shift and/or engagement concerns and/or possible damage to the transmission. High fluid levels can be caused by an overheating condition. 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 Maintenance product specifications and capacities section in this chapter. Note: Only one ATF fluid specification has been tested and approved for use with the automatic 6-speed: Premium Automatic Transmission fluid. Mercon fluids cannot be used with the automatic 6-speed without damage or voiding warranty. 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. 302 2012 MKZ (378) Owners Guide, 2nd Printing USA (fus)
