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