My 91 manual transmission prelude won't go into gear and drives only in neutral

Hello, this question doesn't make sense in that "neutral" won't engage any gear. If you're saying it only "drives" in "neutral", then I'd say that when you expect "neutral" you're actually engaged in a gear. This leads me to be concerned perhaps about the shift lever fork engaging gears when not expected. Something physically there that needs to be evaluated.
