Whats the Power switch on my 89s shift selector for?
The power switch was only available on the 1989 Probe GL & LX models with an automatic transmission. This switch allowed the driver to select from Normal Mode and Power Mode. In Normal Mode, the engine’s shift points were conservative and were designed for casual driving with fuel economy in mind. Power Mode has higher shift points and more aggressive shifting. This mode was intended for faster, higher performance driving. In 1990, the switch was replaced with a shift lock.
