Hi everyone, I'm trying to figure out what tranny oil cooler I want but I'm running into more confusion than fact. Transmission is an E4OD I'll be pulling a 5th wheel weighing around 13k loaded. When researching for the coolers I'm finding Tube and Fin, Plate and Fin, and Stacked. Fancy words like Rapid cool or turbulators. In my mind I think the larger the better http://www.oreillyauto.com/site/c/detail/HDN1/405/N0940.oap?ck=Search_transmission+coolers+%26+accessories_1124840_2837&keyword=transmission+coolers+%26+accessories but different web sites show this http://derale.com/products/coolers/transmission/series-9000-plate-fin/190f-fan-switch-thermostat-detail Is it all sales hype or is there some truth behind it? One more thing, I am finding that I go to different web sites and the same part number will have different ratings, Ex. Med. Duty-Heavy Duty what ever that means.
