Transmission is driven by the drive belt, and the transmission cable has to engage the transmission when cable is pulled. If the transmission is working, the outer wheel gears or the wheels themselves with the inner gear can be damaged. Just need to check each section to see where the loss of drive is!

Here is link to parts site, showing a transmission for $61.00. But the belt needs to be tight enough to turn the transmission pulley. It would be your choice, but yours is built better than the newer models!
