Hey yall,
So the other day (Thanksgiving) my cousin was showing me around his new 3500 CTD for his daily hauler (construction foreman but thats not important). Anyway after i was done drooling and we started drinking the talking started. He mention having an extra 10 gears and goes 70 hauling a load at ~700rpm. I called bull****, since then i have been searching and just cant find anything about this so i am hoping someone here knows what i am referring too or can tell me it was bull. Anyway he explained it as having his stock normal trans, then there is a controller in the cab for an extra 10 gear trans that is behind his stock trans. Is this somekind of over drive thing? I know i have read about one before but i cant find anything about it now either here nor google. Anybody heard of anything like this? Thanks yall and i will join the proud ranks of a CTD owner soon as i get the money, still in college. <-

 

im 98% sure its bull..a 3500 cant haul enough to justify 10 gears...unless he swapped a 2spd rear...or are you saying he has 15? or 16 then yeah no...and i dont think the cummins makes a crazy amount of torq at 700 rpm to be haulin maybe if it was like 1200 ish
