April 4, 2005I have a 2001 Screw with the Stock Tranny cooler since I got the tow package. I'm running 35's and wondered if an auxiliary (augmental stack I guess) or full-blown upgraded replacement is a good idea or if the factory one is sufficient?? I don't know what temp I'm running now (gauges not in yet) but I do not see any probs so far. I heard you can get a pretty good one from Summit for like $50. Anyone know anything about an "ACCUCOOL" Cooler rated at up to like 25,000 lbs??
