Hey Guys, My tranny seems to be fine so far. I'm pulling 13,500 5th wheel toy hauler around the country. My old friend told me that I'd better think about heavy duty billet tc and maybe a tranny beef up to head off any future problems with the 4r100. The truck will pull it, but hills and mountains kill me. I just think the 7.3 should pull a little better than it does............any thoughts ?? I guess the ? is, what would a new tc do for me ?? Another buddy recomended a suncoast tc.
