1996 Ford F-250

Transmission problem
1996 Ford F-250 V8 Four Wheel Drive Manual

I have a 1996 f250 7.3 powerstroke. Just within the past couple days I have had a few problems. First the 4th gear went out, I can still get it in that gear but it grinds really bad. Someone told me it could be a clutch plate, but not sure. Second issue i've been having is it will start making a wierd noise and lose power but then gain power right after. And now the front end is starting to shake as well.
