I just got a buggy that had a 3 speed auto vanagon trans but had no way to cool it. I took the buggy out this past weekend and when I got to the top of some long hills the trans started to slip. I felt the trans and it was HOT. I did some research and found that there is a way to hook up an oil cooler the original oil/water cooler part of the trans. The part that confused me is that the trans that I have does not have thoes ports in it. I am left puzzled on what I could do to add an oil cooler to this trans. As it really needs it.

Here is a link to a pic of the trans.

The aircooled bus had no cooling provision other than air passing over the tranny. You could add ports to the pan and use a pump and oil cooler though.

Using a pump to circulate the pan fluild through an oil cooler will cool it down. Yes

On the vans people would fashion a scoop out of sheet metal to direct more air over the tranny, but that wouldn't work in a buggy.
It probably slipped because it boiled the trans fluid.

Would that destroy the fluid? even though the trans is cooled down it still seems to slip. it goes into Park Drive Rev.. fine and moves but it seems when i mash on the throttle it slips instead of grabbin

I'm not an automatic guy but it sounds like you screwed the pooch on that one.
