So recently I've noticed with A/C and radio off that my Civic would produce clunk sound whenever I shift the gears. Obviously clutch depressed all the way and when shifting into gear it would make a faint clunk. If hold the clutch pedal depressed for 3-4 seconds - no noise whatsoever plus much less resistance going into gear. Now, car has 22k miles right now and transmission was never really smooth in terms of shifter feel, you can call notchy I guess. amount of the resistance when going into gear hasn't changed at all. Although, I don't know if the clunk noise when the gear is engaged was there before or it developed recently. That being said, I kind of expect that there will be some resistance when fork is moving the synchro and it engages with the gear. I guess my question how much should I be hearing? Also, what concerns me is that there's no such sound whenever i hold the clutch disengaged enough for the input/counter shaft to slow down/stop (sitting in the garage with the sound reflecting from the walls I can tell when they stop). What do you guys think? Is that a synchros going out? Or perhaps a motor/transmission mount? Have you been hearing similar noises with your manual transmissions? Thanks for y'alls help
