Push the button to down shift. Why you'd want to do that other than driving down an incline I have no idea. It's an automatic, not a manual, no need to throw it in gear before corners. Bit if fun I guess. BEST factory shifter out there in the day, easily. It's still better than the cable junk you can buy today. Hurst & B&M both copied the
Slap Stik (no C in Stik) design. Steel rods, precise super fast detent shifter. Can't ask for more in an auto shifter. Many guys will tell you a Slap Stik equipped car would beat a 4-speed at the strip and a lot of guys ran them in the day for that reason. Who knows, but, as far as shifters go for E-Bodies, we hit gold lol.
