Dodge Ram 3500 transmission will not shift
I got a 2000 dodge ram 3500 dually 5.9L auto, I didn't have any trouble with it when I parked it. It sat for about 3 weeks and I drove it one day and it went into gear fine but would not shift to 2nd or 3rd or o/d. oil level is good. It goes into all gears but will not shift. I pulled the cover off the fuse box in the engine and the transmission fuse relay was really hot, would this keep it from shifting if its bad? Anybody got any ideas.
