Got me a 2500 gasser. Got some questions for those who tow big loads in Hemi's like I plan on doing. Engine seems to definitely have the balls to get the trailer up the hills (when rpm is appropriate) and the truck brakes/suspension are great. It's the auto 55rfe that needs attention. Supposedly my truck's computer is unique so a tuner isn't really an option (info on this)? Basically the issue at hand is when pulling hills the trans goes down to third gets to wanted speed and then shifts back to 4th which is not an optimal rpm range for climbing hills. Any way I can make it stay in 3rd when climbing hills? People are going to say go to 4.56 and that would be great but to do that would probably cost me more than I payed for the rig. Tires are 265/70r17 stock size bfg ko2 ats. Trucks got 238k so tired but runs really good and shifts really good. Im all ears if yall got any other future tow mods that don't cost a fortune for these trucks.
