Seriously... 'marnold6'... I was about to ignore... Then I noticed the obsessive, nerdy nature of the questions.
I don't think the JGC case is like that, it is 48/52 front/rear IIRC by default, but can push forward and backward if need be (sort of subaru-like as it's clutched rather than audi gear driven).
Some JGC lower trims stay as such, other allow the locking feature.
