Transmission build date?

I have a 518/46RH I was told was a 92 or 93 I am trying to nail it down exactly.

The pan rail reads

53008102 0548 8196

I believe the 0548 is the build date code.

When was it built?

Thanks!

I think the 8196 is the build date ?

0548 is the build date but since lightningjar is gone there's no way to look it up.

The previous 10,000 day calendar ended on 12/13/1988 so 548 days after that would put it around June 1990.

Thanks John! I was starting to question the date I was told. I found a 91 truck today with its original transmission and a higher number. The number was also stamped in a way that looked like a dot matrix, mine is solid stamped numbers. Also mine didn't have the crank sensor cut out, and the 91 did.
