I daily drive my tw at least 70 miles a day, recently it developed a REALLY bad noise whenever I give it any gas in 1st-4th gear. If I keep the rpms really low then it does fine and in 5th it works perfect. At first I thought it was my chain hitting something, but it obviously wasn't. A friend of mine said it sounds like its trying to come out of gear, maybe a broken tooth on the transmission? I read that these transmissions can take a beating, and mine only has 8000 miles. What else could it be? I also have a parts ttr225, so if its something major I could just make it a six-speed. Any help is appreciated!
