I have had positive experience with the 6spd auto in my G8. The only thing I didn't like about it was the factory programming. Shifts were sometimes slow and the tap up/tap down feature was too sluggish to give you a decent manual/auto trans feel.

I never had any issues with it hunting for gears but if you wanted something drastic to happen, it was very dependant on how deliberate you were with the throttle. This wasn't a glaring issue but you had to really provoke the car for a nice 6th gear to 2nd or 3rd downshift.

I've modified all of these parameters within HPTuners and have gotten quite good with the trans tuning which is very very complex. Durability wise, my first hand experience is that I haven't had any issues. I'm not a track rat but I have over 30 passes on the car banging gears and have noticed no degredation in how the trans runs or functions. A lot of the stock tuning lag, primarily when shifting at WOT, is due to torque management. People are able to now tailor how aggressive tq mgt is at different rpm and throttle levels. If you are just driving around like a normal person, the stock tuning is fine. I just wanted a crisper and more deliberate feel.

Guys are strapping boost to G8s and the trans seems to be able to hold it. Guys are still using the stock trans and already in the deep 11s if not high tens, granted the only mod I'm aware of is a higher stall converter. I'm not sure how long the trans will last in these configurations but they seem to be holding up.
