Figured I'd update. Suprise...dealer isn't concerned yet. It's a pretty annoying whine but the transmission at least shifts/feels great. They told me to come back after 1000 miles, so we'll see. I may not worry about it since this car is likely to make big power in the future and I'll upgrade it anyway. We'll see if I can still hear it over my full SW exhaust.
Mine has a little whine to it under light acceleration, and for the MT82 its pretty much considered normal. I just swapped to Amsoil MTF + XL-18 additive and it quieted it down a little but it is just the nature of the beast with these units. Once my cat-back goes on I'm sure I wont hear it at all.
I had no noise before about 5000 miles and a lot between 5 and 15000. Primarily 4 gear between 1400 and 2100. Had a very mechanical click from 1 to 2/noise similar to problems previous years of gt 500's and 5.0s have had... now at 30000 I have only intermittent mechanical click from 1 to 2 and that sound from 1 to 2 under partial throttle shifts.
