Hello fellow jeepers! So I'm looking for a trans cooler for my 03 Rubi. I don't want one with a fan. Just one that goes in front the rad. Any suggestions on size? And do you add it before or after the rad cooler? One last question. Is there any things that I mite need that wouldn't come with the cooler? Thanks
you can get basic ones from autozone, bout $40 for a decent size one, youl want to get a little more 3/8 TOC hose, and a couple of double sided barb fittings with hose clamps, more trans fluid(duh) and youl want to add it after the factory cooler.
May I suggest B&M 70264. It's top to bottom measurements let you slide it through your headlight opening but it is thicker than most and rated at 14,400 BTU I beleive. I just installed one on my 2005 TJ two months ago. It comes with a lot of mounting stuff you may or may not use. There was not enough line as I wanted to mount mine with the inlet and outlet facing up as instructed by most. Mount it to the V bracket, I used insulated pipe brackets but I saw one guy just use self tappers with rubber washers? Don't mess with trying to use their brass fittings either, use 3/8" double barbed brass fittings and GOOD hose clamps splicing into your transmission line. The correct one is a debate but I used the return line (post-radiator). You won't lose that much fluid but with the extra line and the cooler, you will need a good quart to get back to full.
Before or after the OEM cooler in the radiator is something you have to decide for yourself. One school of thought is simply that cooler is better. That would suggest putting it after. Another way to look at is though is that perhaps there is a proper range for temperature and getting the fluid too cool is not a good thing. That would suggest putting it before and allow the two coolers together to get it into that proper range.

The 70264 is a good cooler than many use. As for the area you live in and that you see cold weather for any length of time, I suggest adding in in before your radiator. If you add it after the radiator is may get too cooled in the winter months.
