Maintenance and Specifications Checking automatic transmission fluid at cool temperature (32°F-81°F [17°C-27°C]) If a fluid check is necessary at a low fluid temperature (32°F-81°F [17°C-27°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. High fluid level Fluid levels above the safe range may result in transaxle failure. An overfill condition of transmission fluid may cause shift and/or engagement concerns and/or possible damage. 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 6-speed-Premium Automatic Transmission fluid. Mercon fluids can not 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. 264 2007 Montego (mgo) Owners Guide (post-2002-fmt) USA (fus)
