Does not move in reverse without pressing the accellerator
I had a very strange issue happen last night and I am getting ready to go out for a trip towing 15k. I went down to re-fill the fuel in the truck, and i was backing up in my driveway and it was backing up fine (idling), then it felt like i bumped a block or something and it came to a stop.
Then I pulled forward, got out to move the peice of wood or something i hit and looked, and there was nothing, so i got back in, put it in reverse, and it went about a foot and then it felt like the same thing. SO, I gave it some of the pedel, and it started moving, but then as soon as i let off, it came to a stop.
Clicked it over to drive, and it pulls forward great, but as soon as i go into reverse, it stops and when i accellerate, it feels like something is dragging.
Any ideas of things to check, i gave it a quick once over and even felt all the brakes, and one didn't feel hotter then the others like it was dragging.
