Up until Ford built it's own diesel (the current 6.7) in 2010, Cummins/Allison was the engine/transmission combo used in the medium duty trucks. I worked at a Ford dealer and a few F-650's/750's came in for warranty transmission work or engine work and we had to send them to Allison or Cummins as we weren't certified to do any warranty work on either.
