I pulled my transmission out becuase the truck with a decent tune (idle screw included) will creep foward upon starting and idling and die after a couple passes, not even at full speed or breaking. Traxxas told me to check out the transmission and see if anything is up. When pulling it apart the only thing I noticed was a warped/bent (?) brass spacer. Is that spacer supposed to be bent a little or is that the culprit? Otherwise, I am stumped.
