So, I was driving back home from work and finally got off the turnpike. After I got off the turnpike, I hit the traffic and there I noticed. It only happens in 1st gear just as car starts to move. As I slowly let go of the clutch I can feel and hear(just enough to notice) clunk. Sometimes just once other times twice or three times. It seems and feels like it's coming from transmission or transaxel. My car has just over 50000miles and over 90% is highway driving. Anybody had same experience?
