Maintenance and Specifications The transmission fluid level should be targeted within the cross-hatch area if at normal operating temperature 180°F-200°F (82°C-93°C). High fluid level If the fluid level is above the MAX MIN MAX range of the dipstick, remove fluid to reach the hashmark level. Note: Fluid level above the MAX level may cause shift and/or engagement concerns and/or possible damage. High fluid levels can be caused by an overheating condition. If your vehicle has been operated for an extended period at high speeds, in city traffic during hot weather or pulling a trailer, the vehicle should be turned off until normal operating temperatures are reached. Depending on vehicle use, cooling times could take up to 30 minutes or longer. 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. 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 MIN MAX should be removed by an authorized dealer. 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. 377 2010 Flex (471) Owners Guide, 2nd Printing USA (fus)
