[QUOTE="Jack Hidley, post: 13848171, member: 17703"] Some updated information. QuickTime now has a RM-8087 bell housing available that bolts the 3.5l/3.7l engine to an aftermarket T56 transmission (the models with the midplate and hydraulic throwout bearing). I do not believe that the 3.5l Ecoboost engine will need a vacuum pump for vacuum assisted brakes. The vast majority of turbo cars with throttle bodies that have vacuum assisted brakes, do not have vacuum pumps. In the case of the F150, I suspect that Ford installed one since the engine may be at high load (positive intake manifold pressure in this case) for long periods of time when towing. Without the vacuum pump, the vacuum reservoir could run out of vacuum. One thing that is interesting is this. The S197 Mustang has two different versions of the MT82 and 6R80 transmissions. This is because the Coyote engine uses the modular engine bell housing bolt pattern, but the 3.7l engine uses this new 3.5l/3.7l bell housing bolt pattern. [/QUOTE]
