Since the definition files used for each are the same (EBM1/PMT1 are VRAA6 and the EBM2/3 and PMT2/3 are VRAA7) I would assume that the shift characteristics would be very similar.

There are certain aspects of PMT1 that are better. With the way my wife and I drive when unloaded, we would never know a difference. The differences really start to show up when towing (as well as racing...so I hear...but we don't do that). Namely the forced 4-3 downshift TC strategy and the WOT lockup.
