Jerry:

That is a good question. I would think if the pinion or ring gear in the differential would have gone bad, it wouldn't move at all. In the transmission is what is called a planetary gear. It is called that because there are 3 gears that ride around another one to give you reverse when the low / reverse clutch is locked. Based on what you are saying, it sounds like that may have come apart. That sad part... it is the farthest gear back in the transmission before the sprag gear which is for park. If you can, have a helper start the vehicle, place the park brake on and hold his foot on the foot brake so the car can't move. Listen under the vehicle to see if it seems like the noise is coming from the transmission area.

Let me know what you find.

Joe, Do I need to put it in any gear to check where the noise is coming from or just start it with the parking & foot brake engaged and in park? Jerry
