Just curious about what trans are preferable in what applications and why. Most truckers around here are running 13 speeds, or other Roadrangers, like 10speeds. I think the Mack 12 speed is popular now, too. Just a hypothetical question, if you were spec'ing out a truck (that you had to drive yourself) which transmission would you prefer in, say a triaxle dump? (80000 gross weight). Or a tractor to pull a lowboy? Or pulling a dumptrailer?
