We have a new noise at 45 to 50. It is a hum/whine that comes from the dash. At first we thought it was some sort of wind noise but it seems to be coming from the speedometer area. I know the element does not have a speedometer cable but it sounds a bit like lube problems in older cars. By 55 it goes away. It continues when we clutch, let the rpms go down, and coast. Anyone have a suggestion or guess?
