FORD 2006 F-150 v.2 - Manual (Page 321)

2 Ensure the correct automatic transmission fluid is used. Transmission
fluid requirements are indicated on the dipstick or on the dipstick
handle. Check the container to verify the fluid being added is of the
correct type. Refer to your scheduled maintenance information to
determine the correct service interval.
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.
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.
