Joe,

Can you give a little info on the sound. Vibration, grinding, air, etc? At what point (RPM/speed) does it show up? Does it occur in all gears?

The vet has 5000 miles I don't know if its a grind or a soft bang ????It happens at about 6ooo rpm when it shifts between 1 and2 and 2 and 3. only at WOT???
