When i received the shifter, it would rattle in SQ mode. Rattle went away once put into H mode. Had to open the shifter up and make a gasket where the screw pivots with the mechanism that switches to SQ to H mode or else the metal piece would rattle ontop of where it presses against a metal button/knob. Other than that i love the shifter. Shifts are solid and percise, nice thunk into every gear
