I bought a '89 with a W56 trans in it about a month ago. Yesterday it started kicking out of 1st and 3rd gear. Today 1st seems alright but it wont even go into 3rd without pushing the shifter hard and holding it in place. Does anyone know whats probably wrong with it (shift fork?)? Is this a common problem? I spent the morning calling junkyards and could only find a W56 through a parts locator service for $800 including shiping. Does anyone have any cheaper suggestions on fixing it.
