 continues with the Julian date until December 31 (365).  The sequence then continues until the end

 of the 1985 production.  EXAMPLE: January 20, 1985 would translate to a build date code of 385.

In addition to the transmission production code number, all passenger cars have a portion of the 

vehicle identification number stamped on the transmission.  The condensed vehicle identification 

number consists of the division identification number, model year, assembly plant designation
