......Call your dealer! Only way to know for sure is give your VIN.

New torque converter installed. No difference in stutter at 61 mph and above.
They thought TC was maybe not locking. Not the case or new one is bad too.
It could be a million things from bad universals to engine management not giving correct fuel.
Car goes back to them today. They have an engineer coming to drive it and see what he can figure out.
Tranny shifts and such are not perfect, but I can live with the little misshifts and such if the stutter would go away.
To be continued......

Don't think it is for the '08. They stopped at '09 for some reason. The only update for the '08 is the last one they did last year.

You have a MANUAL. What would a 7AT software update have to do with a manual? You're the one doing the shifting...
