Please help ID my C6. I need a Neutral Safety Switch in Engine, Transmission, Drive Line, Etc Posted June 9, 2016 Bah! I bought a new NSS but it doesn't fit. The shifter shaft doesn't have the 2 notches to index the NSS. There's no way I'm going to drop the tranny in order to swap shifter linkages - at least not this year - so no backup lights for me. Now Id like to figure out how the PO bypassed the neutral safety switch. There's no jumper on the harness/plug on the back,of the motor....?
