Is there a complete Trans Cooler setup that I can replace the factory one with. I have seen these secondary ones that guys are mounting under the bed. But how about removing the cooler altogether to replace with a aftermarket one. I need a new cooler and rubber lines on my 98 auto 24v cummins. It was in a wreck and the previous owner scabbed everything together and it just started leaking again. It is strictly used for towing. Can I fine one that mounts under the bed, or should I try to find the factory one in a junkyard.
