I have a vibration in the engine that I want to get rid of and I have 3 T5 WC's. One is in my car and the other 2 are spares. The transmission is the weak link in my drivetrain I'm going to rebuild one of them set up to handle more power and torque so I don't have to keep any spare transmissions hanging around. I couldn't afford to pay myself to work on my car at my hourly rate in my real job but that isn't a bad idea if I could use it as a tax writeoff
