Default 4+3 transmission pan number tag?

Does anyone know what the little aluminum metal tag is for with a number on it # (4J09951) that is held on under one of the pan attaching bolts? I took mine off as I had a fluid leak at that bolt. The bolt there was a little loose. I then snugged up the bolts hoping the drip will stop. Is it a serial number for the Doug Nash transmission?

Production date code and unit # is a maybe. @ihatebarkingdogs will likely stop by to explain but what year is your car, what is the date on the certification label (drivers door). Do you believe it is the original.
