Is this the plastic style transmission?
NVM, I have viewed the transmission. With no speed, it could be one of several different issues. #1 is check the belt. #2 is check the clutch pulley assembly. one of the 2 are most likely the issue. These transmissions are known for going out. It is a $600 transmission as I have had to replace 2 of these this year so far.
What do you mean by how much movement up/down? The one pulley is like the clutch on a GO KART. It will slide up and down approx. 1/4"-1/2". I will try to pull vids and/or diagrams from my shop tomorrow for you
Have you checked all several black plastic parts of the pulley to make sure they were not stripped out or broken?
