Re: Performance Shift?
When pressed on it increases shift firmness and allows the transaxle to shift at higher rpms thereby improving acceleration/performance. It does not increase or decrease horsepower as some Grand Prix owners believe.
Also, tranny downshifts occur at a lower percentage of accelerator use while in performance shift. Fuel economy is normally better with performance shift off.
