Its bigger than my Cummins 5.9 6BT. But I prefer the mechanical engines, so I can only go as new as a '97 or maybe a '98. But the Cummins 8.3 ISC is a good dependable engine that you will also find on commercial over the road trucks. Know nothing about the transmission. My choice would be the Allison 3060, but my 19 year old Allison MT643 is still going strong. I think you can depend on any Allison transmission that can handle the torque of then engine. And no manufacturer is going to mate up one that can't.
