Automatic transmission cooler

hello everybody im planning on make a custom trans cooler for my auto. Im getting an extra set of trans lines so I can cut them and make something. My first question is what are good brands of coolers? B&M? And whats better tube and fin or bar and plate? Also does anyone know a good spot to mount this to get good air flow to it? I was thinking about adding a fan to it if it doesnt end up right in the front some where to try and help. Has anyone ever done this before is there a guide for one of these? Also does anyone know where I can hook up a trans temp gauge? cant think of anywhere to put it. Well any help or input thoughts or comments are appreciated so if anyone can think of something to add please let me know

B&M is a known good brand, as is Setrab. I've used PermaCool in the past. http://www.perma-cool.com/catalog.pdf

Their heavy-duty tube-and-fin trans coolers are the same as their oil coolers (external fins with internal "Turbolator" that aid heat shedding). The one I used was 1.5x7x15 with 1/2" hosebarbs and I got substantial oil temp drops. There's ample room in front of the radiator to mount it.

It was part of a earlier engine build and it's not on the car, and is just sitting on a shelf. I don't have any of the hoses and fittings, but those should be easy to source. I was going to mount it in my Suburban but I rarely use it for towing. Price out the various ones you're interested in and make me an offer...

EDIT: regardless of what you decide, here's a pic of the fitment of that size cooler on an NG900/9-3. For a trans cooler, just switch the inlet/outlet side to the driver's side and run the hoses that way...

That's a good picture to give me an idea and I may take u up on that cooler, but did you see the temp go down more than 10 degrees?

I have this on my 98 Taurus, with the AX4N "Turn 40 hp into heat" transmission. Works quite well.

During summer testing, I saw a consistent 20-30 degree drop in coolant temps, even during repeated "testing" runs at WOT. Anything you do to keep the overall fluid temps down will help. That's the rationale behind the existing exposed metal loop for PS fluid....

20 to 30 degrees is awsome, hopefully I can do something like that. I hoping to locate the cooler the same place you did mike because I think that will be the biggest spot I can fit one. And pimp what do you mean turn 40 hp into heat?

LOL....Mid-90s Fords were notorious for tranny issues from overheating. I had a 96 Windstar that hated the heat.
