So I was at dealer today to pick up some parts for my PM and I thought what the **** I would kill some time and test drive a diesel PM again with the automated manual transmission because I been thinking fuel mileage not that great with the gas version with my driving habits, and I thought maybe just maybe diesel the way to go long term. The transmission sucks on this powertrain! The durability is probably awesome, but the drivability is absolutely awful! The shift points were erratic and rough. Honestly, I am not sure what the diesel PM owners like about this transmission? I had a Sprinter with the 7 speed Gtronic trans and thought is was smooth as silk! I think I will stick the the gas version of the PM- the engine and trans are extremely smooth and quiet and love everything about this van with the exception of the dealer support.
