I drove a 2010 International box truck for about 8 years , it had the automatic trans with no park which I found odd, the truck was very troublesome but it didn't need DEF fluid somehow International got away from needing it that year, the company traded it on a new Idealease one about a year or so before they let me go , it did take DEF and seemed to run better its had a Cummins diesel whereas the old one was an International. In the old truck I was coming back to N.J. from a delivery on Long Island on the L.I.E. and the truck just died the muffler was red hot, I let it cool down and the truck still wouldn't run and ended up getting it towed something went wrong in the regeneration system. I think we used rental trucks more than the 2010 box truck as it was always in the shop same goes for the 05 International tractor they bought to pull their tanker trailers always in the shop and breaking down.
