FJ60 1984. Recently changed transmission oil, gear box oil and engine oil and the sound existed prior as well. While accelerating at a high speed or on even small hills there is a high grinding / screech like sound - that is heard only when I accelerate. Often the car also slows down when I’m going up a hill. Very confused as to what it could be. Any ideas or similar experiences out there? Would appreciate any help!
