Where can i get the biggest aftermarket trans cooler that goes up front on My 2nd. gen. I have 350 hp and tow 21,000 almost daily. I have a b&m under bed one that is by itself (i removed stocker up front) and it does an ok job but i have to run the fan a lot to keep it under 200. Its a 96 3500 2x4 dualie. It has got mag-hytec double deep pan on a $7k BD Full roller bearing trans that is bullet proof.

 

More important than the size of the cooler is the restriction it will place on flow. Get something with 1/2" lines. I've seen a couple different ones like that at Summit.

Also if you haven't already got one, consider a Mag-Hytec double deep pan.
