So which exactly is the redesigned clutch and where can I get it, also today when I was driving, as i accelerate i hear like a loud "fan" type noise and when i went to around 3.5 RPM is stopped and then it did it again a lil while later and it hasnt done it anymore. In low rpm is when it did it. Could that be a tranny issue where the motor was just spinning with gripping or could it be just a fan blowing
