MISSING METAL PART/PLATE UNDERNEATH CAR

Buick Riviera

I own a 1991 Buick Riviera. It is a 6 cylinder I believe and has 100,108 miles on it. I had the Transmission rebuilt 3 years ago. To my knowledge it is not slipping however I noticed within the last month some leakage about the size of a qaurter each day. My levels have not gone down when I check the fluid. I also noticed a metal clanging noise occasionally when I would hit bit bumps or potholes starting about two weeks ago. I do look under the car daily and see build up (1 or 2 drops) on a metal plate directly behind the front bumper on the drivers side. I noticed today that the plate is missing. There is no puddle or sign of any major transmission fluid leak and the level once again seems fine and the engine turned over, I did not drive it yet since I noticed but am sure I was driving when it came off. I am concerned if it is damaging to my car or to me to drive it before I can get this checked. I do not think this is the transmission pan. It seems to be an access panel because there is a pipe up in there. I also feel a bolt that does have some fluid on it. I am not able to get all the way underneath the car. Can anyone advise me or tell me what this plate is? Thanks
