What transmission?
aod= dexIII/mercon
4r70w merconV
e4od/4r100= Mercon
5r110w= Mercon SP
most other ford transmissions use mercon V or it will supercede what it had originally.
SP is very expensive, supposedly I was told it is just super refined mercon because the 5r110 is very sensitive to any particles.
