shift kit has loud 'bang' between gears....sounds like a brick rolling around under my car..plus I hear some kinda 'Winding' noise..but only when I got 'Transmission Perform(shift kit) on.....in normal mode it shifts great no problems or 'bang' sound.....what the heck?....anyone know what this could be before I head to the transmission shop where God knows what shit they'll tell me.......bad luck this week with my TA
