Past 2 weeks there has been a vibration above 55 - I thought it was U-Joint, there is a little play. And, it started making a clunk (more like a metalic clink) when going from rev to Drive - But, the clunk really sounds like it is in the trans...
B4 I got around to replace the U-Joints, now when i put it in gear, Drive or Rev, the trans makes a whirling-whining sound going into gear, it goes away after 5 sec. It also makes a steady similar, but quieter, noise in Park. It still shifts fine.

I checked level and found it was low, so I added 2 quarts, but noise did not go away.

I got year ago and never changed fluid or filter.
