I was driving to my girlfriends house today when I noticed my speedo had stopped working. The truck was running fine so I didn't think anything of it. When I got on the highway and got the truck up to speed she wouldn't shift into overdrive. No matter how high I revved the engine it wouldn't shift. So I finally got to my girlfriends house and let it sit for a couple hours. When I got back in to leave, the sppedo was working again and she would shift into overdrive. Sorry for the long post but any ideas on what could have happened and why it fixed itself? I guess its time to put in a 5spd
Thanks again.
