Clutch in at red lights? Keeping the clutch pedal pressed in at red lights is not necessarily a bad thing, but it puts more wear and tear on the throw-

What if the speedometer cable gear has fallen into the transmission? Do your best to get it out. A lot of folks have never had issues with roving speedo gears, while others have needed repair work due to the gear (or parts of it) getting jammed into transmission components. Don't become a victim of the latter.
If the clutch pedal is difficult to press, replace the clutch cable (don't bother trying to adjust it; it's a $16 part... buy it, install it, adjust it to specs and drive happily ever after). While you're at it, inspect the clutch cable carrier tube at the firewall (this tube can fail if the cable is not adjusted at regular intervals and/or if a stiff cable is allowed to saw through its protective sheath). If the tube is found to be broken, it'll need to be repaired.
