Ok im going to try to make this a s short and sweet as possible my 02 cummins had a hard time shifting into really any gear but mainly first and reverse. When i checked out the clutch it was bad due to the fact that the previous owner didnt not resurface the flywheel properly it looked like they just used a wire wheel to clean it off. So i replaced the clutch. This didnt help the shifting issue i have tried pumping up the clutch that doesnt help the transmission doesnt grind slip or pop out of gear. I need some suggestions

 

You truck probably has a bad pressure plate. I would advise you to get a pressure plate from Dodge or a vendor that sells OEM parts, as parts store pressure plates often have problems and are just not worth the hassle.
