I may be looking for a frantz for ATF bypass. Only thing I am worried about it converting back to stock while still under warranty. Oil filter is as easy as removing a sandwich filter, but the ATF will be a little more difficult.
I think the Motorguard would work better for oil, because it is easier to change with the T twist on and off, but the ATF filter, needing to be changed less, will benefit me in the lower price.
