So I have lately noticed that intermitantly when I try to power shift my 465, the truck kinda shakes a bit like maybe the clutch is slipping. This only happens when going into 3rd gear (2nd for those with L-1-2-3) and it doesn't do it all the time. Sometimes the same thing happens when I down shift to use my engine rpms to slow down. I am not sure how old or how many miles are on the clutch. My thoughts are that maybe the clutch is wearing out but I'm not sure. Any thoughts?
