The truck is a 95 ford ranger with a 5 speed tranny. When I left for work this morning, I started my truck to let it warm up. When I went to back out of the driveway, I put it in reverse but the truck wouldn't move. It would just rev up and feel like it wanted to move. No, the ebrake wasn't on. I put it in 1st to see if it would go forward, but had the same issue. What could cause this? Tranny/clutch issue? Now just a couple minutes ago, I started it up and it worked fine. Could it have just been the cold? It was like 30* out, not that cold. Weird.
