Don't be too sure about this. Initially, all the big three were using whatever transmission was offered with their regular and big-block gas engines with their diesels.
The ensuing carnage is what induced GM to offer the Allison behind the Duramax and Ford to develop their Torqshift. Those early transmissions were not up to the continuous high levels of torque and the horsepower wars only made things worse.

Diesels develop a lot more torque at lower rpms and require a different set up in their transmissions because of it. I am sure there are some Dodge Diesel related forums you could find out anything you wanted to on your truck. That bad boy should last a good 350,000 to 400,000 miles.

This is true, somewhat. The diesels available in pickup trucks are considered high-speed diesels. The transmissions for them do not have significantly different gear ratios than the transmissions for gasoline pickups.
The main kicker for our dear friend Randy is that, while Dodge may have developed a new and improved tranny for their Cummins, they would still be making it at the same old Chrysler transmission factory that has yet to impress anybody.
Randy, I hope you have no trouble whatsoever.
Brian's Truck Shop can turn these hopes into reality, at least for your transmission.
