So I recently picked up a 56 Dodge pickup that was 2 hours away. After trying to get some people to let me use their stuff, nothing came up. So off to U-haul I went but I didnt want to pay $.49/mile for a local move and have to drive around 250 miles. I rented the truck anyways and had some fun with it when I got home. It took me awhile to find because I was assuming it would be on the tranny, but I tracked down the speed sensor. Since most newer vehicles use electrically signals and not mechanical speedos, its an easy disconnection to unlimited free mileage. Try it next time your making an intown move. This trick saved me over $120!! The speed sensor ended up being on the pumpkin in the rearend. The truck was a Ford F-350. It took like 3 seconds to disconnect the sensor and another 3 to hook it back up when I got back. I only clocked 25 miles, but drover over 250 because I got lost finding the truck. Anyways, just a little tip to help my fellow mustang friends. Have a good night. P.S., dont mess with the connections to the tranny or you'll mess with the torque converter, lol, man that thing started stalling at 3000 like a dragster,lol!!!!!
