Man do the easy things first...change the oil filter to the black chrysler one...put back in 0w40 m1 oil...change tranny fluid with 3 qt atf+4...change differential fluid...IF that dont take care of the noise it could be throw out bearing...clutch or tranny related. OR run the **** out of it and fix what breaks...
It's the part about something breaking that worries me. I had the oil changed not too long ago, so that is also a possibility.
