So what's the consensus on tranny cooler size? I don't remember who but somebody said at least a 24K. A couple other guys say the 40K is needed. This ride will for the most part be the family ride. It will pull a 23' camping trailier maybe a half dozen times in the summer. The 40K cooler is 50 bucks more than a 28K cooler. If I do the shift kit too the 28K cooler is more within my budget. Would it be an improvement over stock or a waste of time and money? If I go with the 40K cooler I probably wouldn't be able to do the shift kit. Comments?
