Has anyone else have this problem? I have a 2005 roadster with 43,000 miles. Third gear seems to "flatten" out when I "goose" it a bit. The rest of the gears are fine, its a little weird and happens all the time. The RPM's drop and them shifts into fourth with no problems with the other gears. It doesnt seem to happen in AutoStick mode. No codes were thrown the last time I was at my dealer. Any help is appreciated.
