I remember that the slave cylinders on the old manual cars that I drove back in the 60's and 70s were almost always on the outside housing of the transmission/clutch and were easy to bleed or replace. If I remember correctly, it was a very similar placement to the one shown on the following:

To me, putting the thing on the inside of the bell housing is crazy, and has been proven to be so, but it must be great for stealership service departments, regardless of who's paying the tab.
I've driven both manual and auto 350Zs and
AFAIK there are no paddle shifters available on their autos. You must momentarily blip the selector forward or backward while its in the "sport shifting" position. The one thing I noticed on the autos was how fast they shifted going either up or down. They transitioned and snapped into gear really fast -- far faster than our '10 Outlander XLS auto with its paddle shifters, where there is some noticeable, slippery lag while the transmission completes the shift.
I've just watched some interesting 370Z auto videos.

and here's a pure 0-60 with auto that impresses me:

I doubt like heck that I could manually shift any faster than the auto ......... but I'm more than willing to give it a try and I will do so on our test drive of the base. If the slave cylinder should fail during that drive, so be it. Edmonntonians are enjoying some great summer-like weather, so the walk will be nice.
