I know there are a hundred threads dealing with this problem, but I cannot find a good answer for this problem. I have a 2003 3500 4x4 with the NV 4500 trans. It is my work truck used for hauling new RVs. In the last app. 5,000 miles the shifting has gotten to the point that I just about cannot get it in gear using the clutch. Any gear. I can shift going down the road without the clutch. After reading hundreds of threads on this subject I figured it was my hydros. Replaced that today. Nope, not that. It acts like the clutch is not quite disengaging when at a stop. I can be at a stop and put it in neutral then push clutch in and push the shifter to 1st. It won't go into gear easily but will try to move forward before it actually goes into gear. It's very hard to shift into any gear, either up or down, once it gets going. I haven't a clue as to what is really going on. I don't want to buy a clutch and its the trans or vice versa. HELP, I'm down and out without my truck running...
