Maintenance and Specifications
Some transmission fluids may be labeled as dual usage, such as
MERCON and MERCON V. These dual usage fluids are not to be used
in an automatic transmission that requires use of the MERCON type
fluid. However, these dual usage fluids may be used in transmissions that
require the MERCON V type fluid.
MERCON and MERCON V type fluids are not interchangeable.
DO NOT mix MERCON and MERCON V. Use of a transmission
fluid that indicates dual usage (MERCON and MERCON V) in
an automatic transmission application requiring MERCON may
cause transmission damage. Use of any fluid other than the
recommended fluid may cause transmission damage.
