    Hytran Ultraction is the one in the bottom 2 pictures. It is an updated version. It has a higher oil molecule shear rating for newer transmissions. It is also backward compatible so it can go in older stuff and won't hurt anything.

    I've got a CVT. They are calling for the "ultra action" even though it wasn't out when the tractor was built.

    NH had a lighter viscosity hydrostatic oil for the Bi-directional tv-140. Something 600???? Supposed to wrap all the oils into the ultra- expensive ultra- action.

    If you never get it below some temp the old hytran was good enough for the CVT.
