New Raptor stage2 trans installed a few months ago. I also recently installed a new B&M Composite X ratchet shifter. I think it's the shifter, but during deceleration it makes a nasty clicking sound to where I can feel it. I know Brian said "do not use a ratchet shifter", but Lonnie says they work fine, and I did not read that until I already bought the shifter. It was very difficult to get it adjusted right, and still not sure it is perfect, but it is set properly in "R", OD, and D. Any ideas?
