The only problem with the 66RFE is the larger than normal gap between 1st and 2nd. It is absolutely no issue getting going, but is large enough that you have to stay in 2nd gear longer than one would like when manually downshifting.
The 6.4 in certain situations when engine braking adjust the valve timing to provide additional engine braking. When it engages, it is very noticeable. Just wish the Ram engineers took advantage of this feature more agressively as it is a great benefit.
