I have a whine in my 08 wing with Lehman conversion while going through the gears. Thebest way to discribe isit sounds like an old 49 chevy 6 cylinder 3 speed pickup truck my dad once owned. It's not quit as load but very similar. Anyone else have this. I have had the whine seems like forever and the dealer says it is normal. Is this true or is he blowing smoke?
