Thanks for all the good answers, I found it.
Only I don't know what the "code letters" are for.  Maybe I don't need to know.

  Look at the Date Code in the Trans Serial Number, immediately following the Letter Code:

  The first two digits indicate the Calendar Date
  The second two digits indicate the Calendar Month
  ie: 01 = January, etc.
  The third SINGLE digit indicates the year
  ie: 0 = 80 or 90, 1 = 81 or 91 5 = 85, etc.
  Note: 0's or 1's depend on the Letter code to detrmine 80 or 90 series.

  The serial number follows after this.
