i ordered a clutch about a week ago through Cummins Perfromance Parts. The 3600Street DD. Clutch felt great when i first had it in; Well i maybe have 500 miles if that on it and it keeps slipping worse and worse everyday. Now its gotten to the point where it is super hard to go in gear unless the trucks shut off. Ive checked the hydro for the clutch and its moving the same amount when i had it installed. Seeing if anyone had any ideas tonight before i call in the morning to check anything out.
