I have found a 4500 transmission, and would like to know more about it.... The numbers I have gotten from the tag are as follows. 15627134 08 03 92 GB ? Could this be one of the desireable units? It appears that the top and rear sections have been removed by the evidence of a silicone bead squishing out around there. It looks to be a 2WD version, with a seperate bellhousing. Any information on this possible find is appreciated.
