Ok, E-series experts; When did Ford install the 5speed tranny in the e350 with the v10? I know that 2006 had it. 2006 was also the last year the v10 engine was available in the 12 passenger. I don't think the 5speed trans was available in 2004, but I have seen it in the 2005 diesel 6.0. Did they put the 5speed torq shift tranny in the 2004 or 2005 e350 v10 12 passenger?
