I'm not telling you anything. It is easy to speculate on what could be the cause. Regardless, whatever the case may be, that engine and transmission should not of fallen out. Period.
As much of a diehard fan I am of Fords my whole life, the Transit is a major disappointment to me in many ways. Sure, the engine and drive train issues may finally be worked, especially the guibo issue, but I sm not liking the fact of no engine access from the inside cab via a removable engine doghouse, like the econoline has. And the difficulty of servicing the transmission? No dipstick? Absolutely ludicrous! At least the Econolines have a unrestricted access to the transmission fluid pan, even with a drain plug on the torque converter . And what buffoon thought it was a good idea to relocate the emergency brake setup to next to the drivers seat floor? If you order a Transit cutaway there is an option of having it by the drivers left kick panel, like it should always be. It's just not a very comfortable cab area, imo, nothing like the Sprinter. But I do like the idea of the rear wheel drive, and many other things as well. And the Transit is a nice looking van. Much more than the promaster.
