hey guys I recently put in a new machined sheave and new oem belt with duner clutch springs, weights, slides etc. everything moves nicely when in nuetral however when i shift into high or reverse i hear a humming noise at idle which goes away under load. I also blew up a belt after the install but that was a dayco aftermarket which i think im chalking up to being a POS. It is also hard to shift from high to neutral. I have to shift to reverse then back up to neutral. That and the noise concern me. Ideas?? thanks.
