Mine whines, and regardless of what lubricant is run in it, it is a piece of junk, imho.

Harley transmissions, in my experience, have been a piece of junk long before the Cruise Drive 6 speed came along. However, that opinion is based on things like shift quality (or lack thereof) and not on noise levels. Mechanical devices, unless surrounded by heavy layers of sound insulation, tend to make noise when in operation. If folks want total quiet, I might suggest a highly sound insulated electric automobile with a killer stereo. Or a really good pair of ear plugs.
As far as I can tell, the reason folks have bitched about the 1st and 5th gear noise isn't because that noise is so much worse than previous bikes, it's because the 2nd, 3rd, 4th, and 6th gears are so much quieter than before. It is a shame the MoCo didn't use helical gears throughout, like the Baker solution, but then again if you want stuff done right the first time you really shouldn't buy a Harley.
The response I like best is from LarryB. The sound level difference between 5th and 6th makes a perfect "no extra cost" gear indicator. No sensor needed, no light bulb, no LED saying "6", none of that modern tech. Just use your ears and you'll always know if you're in 5th or 6th.
