No it doesn't as in your telling me this input shalf doesn't have gears on the end of it that mesh with the other gears within the transmission?
I don't see how each gear is always meshed, they are turning at different speeds and would each turn the output shalf at different speeds, when are are not in use I cannot see how they would all be connected, turning the output shalf at the same time. Even if they are, atleast one gear needs to mesh with the selector rod chooses a gear.
