4. The push-button shifter on the GSM-5000 is nice, but the PS-5001 paddle shifter option is what brought us to the party. It includes the paddle shifter assembly (left paddle is downshift, right is upshift), a set of black anodized billet spacers, the wireless receiver module, and all necessary harnesses and fasteners (not shown). The 14-inch Grant GT No. 774 steering wheel was not included.
