Your motor needs to work hard to get your vehicle up to freeway speeds, but it doesn't need to keep sweating once it hits 55. Unfortunately, a busted overdrive switch will stop your motor from easing up, so you'll waste a lot of gas maintaining your speed. Improve your MPGs and let your engine take a breather with a replacement overdrive switch. All of our overdrive switches come with our 1-year lower-price guarantee, as well as free shipping. And, the quality of our overdrive switches meets or exceeds OEM standards.
