something snapped in tranny
 

hey im new to the site and the car.im buying a 1990 nissan 240sx and the current owner says that 2 days ago while shifting from second to third gear he heard a snap and could not drive it after.he says that it cannot be put into gear now.so i was wondering if you guys could help me out because i was thinking it could b the linkage from the shifter to the tranny but i could be wrong because i dont know too much about them.so any help at all would b appreciated.thanks in advance.
