Pro-Line has released a new, fully assembled transmission for the Traxxas Slash (or Stampede, Rustler, or Bandit). It features a new (and very Associated-like) slipper clutch, less rotating mass, and a sealded differential. It even comes with some 5K diff fluid in the diff, as well as a bottle for when rebuilding the diff becomes necessary. But the idler and diff gears are plastic, so this might not be the best upgrade for bashers. Racers should love their new lap times, though!
Street price on this transmission is around $100, and it should be on the shelf at the end of the month.
