Next gen 6 speed manual trans will use a panetary gearbox...basically an A6's guts but with a clutch.

Will simplify vehicle packaging and save some costs.

wow that park feature is pretty weird, do u think you can put it in park while the engine is still running without it stalling?? that would be kinda sweet

Do you think this will make it into the 5th gen Camaro?

i have a feeling you would have to hold the clutch in, unless they have some kind of input shaft disable when in park

I thought that in neutral or park auto's just disengaged the rest of the tranny from the input shaft...

I don't imagine it'd be any different.

In an automatic, park actually locks the rear most sungear in place, therefore locking the output shaft.

now that you mention it, i remember now.

when in N or P the input still turns but the clutch packs are disengaged, and in park there is a little arm that pushes into a gear on the output to stop it from moving entirely

Correct. Basically it has a gear that the arm locks into. Hence why the car will roll a little bit, b/c the slack has to be taken up for the car to actually lock in place.
