After market trans cooler. And yes you could just use the compression fittings that come in the kit but if I don't have too I'd rather not cut the lines if I don't have to.
It's kinda like soldering wires vs using the crimp sleeves. When you solder it you leave it and don't worry about it coming loose. Same with the compression fittings vs the correct flare and inverted flare fittings.

Will do, I was looking for a BD double stack cooler but couldn't find any and needed one quick so I got the single 40 row Derale which I think the BD is just two 25 row Derale coolers stacked. Still thinking of switching just depends how big the 40 row is and how much space it take up in my bed and how well it cools.
