Hi I have a revo 3.3 that won't go forward I have the forward only conversion and when the transmission is out I can spin the spur and have the output shafts move but once u put it in the truck and take the truck of the ground it the output shafts don't move. The motor works fine and when I rev it everything spins flywheel pinion and spur and input shaft but the out out shafts don't
Please help me
Sounds like you forgot to install a pin inside the transmission.
