I had my clutch and throw out bearing replaced under warranty a couple of weeks ago due a defective throw out bearing causing my clutch pedal to click and squeak. I noticed last night that as I was engaging first gear from a stop that I heard a very distinct chattering or shuddering noise. I only heard the noise in first gear as well. I've heard that our stock clutches can make chattering noises when it's very cold outside so I suppose that could be it but it's never made this noise before.
Another thing I noticed was that when I was slipping the clutch a little more going up a hill from a stop the shudder noise was louder as opposed to moving from first on level ground where the noise was hardly distinct.
Any insight would be great. Thanks
