thanks : )
Derale makes coolers with the threaded fittings. I have a 13750, which has the fan mounted on it so it will be significantly more money than a standard trans cooler but I wanted to mount it remotely. I believe you can get the same cooler core without the fan but I don't know the PN.
I used AN-6 stainless braided hose from the trans to the remote cooler and back. Makes a clean install with no leaks once you get everything tight. I had trouble with it leaking at first, but found out I just wasn't putting enough torque on the fittings (I was kind of scared I would tear the thing apart). On mine, the cooler has a female thread (not sure what size) and there is an adapter that sizes it down to AN-6. Depending on what part number you get from Derale, the fitting sizes may be different.
The plastic "pan" you're talking about on the bottom of the radiator is actually a part of the integral trans cooler that is in the radiator. You can eliminate that circuit if your aftermarket cooler is efficient enough, but if it is not up to the job, you'll overheat your trans and that ain't good. Only way to really be sure is to first talk to the cooler manufacturer about what you're planning and get their recommendation, then use a trans temp. gauge to verify that it's doing its job.
Edit: Just thought of this: Do the barb fittings screw in to your cooler? If so, you should be able to get an adapter to the AN style fittings of whatever size you wan to use. I used -6 because it was close to the original size, but a little larger.
Edit x2: Forgot to say, also, that if you want to go to AN fittings, you'll also need adapters for the tranny. If you decide to go that route, I can get you the info on where I got mine.
