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.
