Why would you want to do that. A quality filter in the pan is just as good if not better. The idea being that you have to drop the pan to change the filter. This will cause you to clean the pan, so that you clean any friction material that might appear and on a regualr basis you can see how much material you may be shedding. Just replace in pan filter.

if you have a factory aux ATF cooler, it is in the return line out of the radiator ATF cooler
on 96 4L, the top radiator ATF cooler fitting/line is the inlet side from transmission
bottom is outflow back to tranny
i would bypass the in radiator tank cooler...they often leak coolant into ATF and ruin transm....put on as large as will fit plate and fin cooler in front of radiator and put filter after that cooler

OK then, if your saying the flow goes from the tranny to the top of the radiator, then out the bottom of the radiator, to the aux cooler then back to the tranny, the return line is the bottom one. Thanks.
