I'm considering my options on a remote filter and cooler install for a '94 Ford E4OD trans with the small 5/16 cooler lines. Remote filter is the standard type that takes a 3/4 - 16 threaded spin on oil filter. I'd really like to increase the cooler/filter line size as well. If I mount the remote unit high and use spin ons with a silicone anti-drainback valve can I eliminate the check ball fitting in the cooler line return w/o suffering converter drainback? Dumb idea? Thanks for any input and tutelage.
