I have a 1997 PSD all stock with 194,XXX. E40D no idea if it has ever been rebuilt or not.
since the cold has set in the truck has been running a bit rough. In all gears the truck will consistently make a humming/grinding noise and slow the truck down. it is only at a certain rpm in each gear. i can even hear it do it when idling. after the truck is warm it will still do it unless i shut it of and let it sit for maybe ten minutes and then drive again, and even then it still does it. i have to get on it for it to go away and it makes her real hard to drive. Any ideas? i will try to make a video of it tomorrow morning when i go to work, as it is sort of hard to explain. I am thinking it is the trans because it does shift a bit hard, but maybe the turbo. would EBVP have anything to do with it
