I press down on the clutch pedal, shift from first to second, or from second to third, when letting up on the clutch I hear a clunk sound. No sound when shifting from third to fourth, or from fourth to fifth.
clunk when shifting on 2001 Saturn SL1
You could have an engine or transmission mount that is failing. This can be more pronounced in the lower gears due to the fact that you tend to be accelerating more in these gears than the higher gears. I would suggest a compete inspection of your engine and transmission mounts.
