I have an 82 and I am installing an external stacked plate fluid cooler. From all that I have heard, I will be running it through the radiator cooler first, then through the external cooler, back to the transmission.
Question: On the radiator, which line is the the flow FROM the transmission, the top line or the bottom line?
Thanks!

I can't find an accurate reference, but I believe that the fluid flows in the bottom and out the top of the radiator so it is always full. I will try to find a confirmation of that.

I have removed a number of radiators with external coolers. The fluid flows into the bottom of rad, then from top to the cooler and back to tranny.

Yup...in at da bottom...out on da top.
If I may make a suggestion, tho...why not bypass the radiator completely?
If the auxiliary cooler you have is sized correctly, it will actually cool better if you run it as a stand-alone cooler. On average, they will run about 40deg cooler this way.
btw...the stacked plate design is more efficient than the round tube & fin type coolers. The only drawback is the added restriction to the flow of the fluid. It isn't that bad, but if the cooler gets any trash in it from the trans, it will stop up easier than the tube-fin style cooler.

Thanks for the help!
Joel, I think my cooler is big enough for a stand alone so I could bypass the radiator cooler altogether. I will try that and see how the temps are.

It was always recommended that you use the radiator cooler so the oil would heat up to operating temperature on the cold days of winter. Since we don't usually drive in the winter it is not necessary.

This would be valid in the Northern areas, where it gets a little chilly. Don't see much really cold weather in Arizona, or most of the Southern states...
For vehicles in the really cold areas, there are actually cooler bypass valves built into the radiator cooler lines. They will bypass the rad. cooler until the trans fluid is at normal operating temp.
