I've got a 94 accord ex man tranny (that i'm fed up with) and a few weeks ago i lost my reverse gear.

Story is i used my reverse gear thirty minutes before getting back in and trying to put it in reverse when it woudn't even go INTO the reverse spot... and at the same time realized my tranny leaked oil... UGH. so my question is... does anybody know what could have caused this? i know it could be a syncro ... or even a damaged gear ...but i have a feeling it's something wrong with linkage at the transmission??
