B&N automatic transmission cooler

What us the best way to route the fluid lines on an automatic transmission cooler? Should the line in be on the top or bottom when mounting the cooler vertical. I have hear some people claim that the in line should go on top to have gravity assist in the movement of the fluid and others say it should be on the bottom. The directions don't say which is better.

If your aux cooler is in front of the radiator and the outlets are on the side !!

The Tranny (hot oil) output line, should connect to the bottom ftg !!

You don't need gravity to assist the fluid, you want the standing auto oil pump pressure, to push the HOT OIL UP, thru the aux cooler--the more time it spends in the cooler the better the additional cooling will be--

Make sure you have the correct amout of ATF-4 in the tranny-when the installation is complete !!

fluid in put on the bottom like Jimbo said. his theory I agree with. you want fluid to cool as much as possible via spending time in the cooler. gravity pulls it out faster, so make the pump do all the work
