[Overdriven]

Didn't you have the same problem a few weeks back in another thread? I guess you checked into the one way and the 2 speed like I suggested in that thread? Because if the motor is spinning and the car isn't moving, or moving slower than it should while the motor is revving to the moon, then the issue still sounds mechanical to me. I only bring it up again for clarification of the problem and the previous thread was never updated telling us if the problem was in the 2 speed or not.
