Speedometer not working. I have a 97 4 cylinder 5 speed. I replaced the vehicle speed sensor and that did not fix it. I pulled out the speedo drive gear that the speed sensor goes directly into and it looked good. However there were no gears to be found behind it. I think that they have slid down the trans output shaft or up it. I can’t find any replacement gears online or in my local junkyard. In need of suggestions. Thanks for reading
