hey anyone have a piece of advice as to where to start? Ive got a 52 cranbrook 3 speed column shift... I can start in neutral or in any gear with clutch down, shift through gears fine but as soon as I let off clutch it makes a grinding clanking sound... not the same sound as if I was grinding gears, I can feel it and it feels like its right at center underfront seat...Ive never really dealt with tranny issues so im not sure if theres anywhere i should start... the linkage all looks ok and the car was fine until this happened other day... was driven three or four days a week ... any help would be appreciated
