gary,ill soon be travelling over 2000 miles to tow over 9000 pounds (total loaded weight of trailer) back to billings. 2000 miles is a looong way in 3rd gear. is there _anything_ i can do on my '01.5 cummins that will enable me to safely use overdrive? would a fan blown external cooler do the trick? anything i could do on my '04.5 cummins?......this is why my '02 dually (purchase pending) will have a 6 speed. the cummins doesnt like 85mph in 3rd gear.thanks,

I'm talking about the Cummins, the trannies will hold up to 6000 RPM no problem. Drive smart, and you'll be fine. Downshift when ya would if it was a stick, and the ECM hasn't done it yet.
