I can feel it in the tranny but there is nothing but gears in there so it has to be coming from the motor. The last time I turned it on I did not have this noise but now I do. Any suggestions?

If you adjusted the stops on the shifting servo, you might be over rotating (binding) the servo in one direction or the other. Does the noise go away, or change, if you change gears without the motor running?
