There is some unseen work done inside the transmission. The reverse gear and clutch system was removed. I eliminated a bumch of moving parts, weight and delay in getting the truck "off the line". It has a "forward only" gearing set in it now. When I hit the throttle, the clutch on the motor engages and the truck is gone! I also went "forward only" on my other TMAXX.
I DON'T NEED NO STINKIN REVERSE!
