Tom,
I understand that CAT exited the over-the-road market due to emission compliance issues. Cummins is the only one making suitable engines at this point. As far as transmission, I have no idea other than it might be an easier "fit" between allison and Cummins. Also, there have been some complaints about the ZF rolling backwards if you dont stay on the brake....think the Allison may be a little more forgiving than ZF.
