Chrysler 4th Gear Overdrive-Lockout
* The Overdrive-Lockout is designed for vehicle applications that are overloaded on a daily basis and for durability purposes are best kept out of overdrive. The Lockout switch when activated will disallow overdrive every time the vehicle is started. This insures the vehicle will not be operated in its weakest position even when multiple drivers use it. With the switch in the off position (OD Normal) complete normal operation is resumed.* Will service Chrysler A500/A618 RH & RE thru 1998.
