How Dow change a speed sensor in a 98 Chevy cavalier 3 speed?

To change the speed sensor in a 1998 Chevy Cavalier with a 3-speed transmission, first, disconnect the negative battery cable to ensure safety. Locate the speed sensor on the transmission, typically near the output shaft; you may need to remove any obstructions for access. Unplug the electrical connector, remove the retaining bolt, and pull the old sensor out.
