i have a 1.7 diesel uno, suddenly im having problems shifting the gears, i can only shift to the gears when the engine is off. i tightened the clutch cable, the clutch pedal went up, and theres only a very slight improvement, i can shift to gears but there is a cranking noise. i dont know much about cars but my dad says it be the clutch disc, pressure plate or release bearing. please help.
