Do you remember KITT from the famous television show Knight Rider? It was a black Pontiac Trans Am that had its own personality. KITT even drove itself with its advanced technology. While you can't expect your car to drive itself around the neighborhood, you can settle for the next best thing—cruise control with a well-maintained cruise control lever. The cruise control lever is an actuator to your cruise control module. This is an input parameter of the transmission control unit present in virtually all makes and models that have an automatic transmission. It takes into account the throttle of the vehicle to eliminate the possibilities of unexpected gear changes whenever the cruise control function is engaged. It is important to control these unpredicted gear changes because they will severely affect the vehicle's throttle, making your ride less efficient. If you continue to use a damaged cruise control lever, it will be more costly for you in the long run. That's why you should get an OEM-approved replacement when you see early signs of underperformance. And to boost your savings even more, you can opt to perform it as a do-it-yourself (DIY) project in the comfort of your garage.
