They are from the same FAMILY of transmissions and LOOK identical. Lots of detail changes that the TCM (transmission control module) can't possibly deal with. A 2002 can't even have a 2003 transmission with the same model number because of those detail changes in TCM programming to match the changes in the valve body design.

I have never heard or read of a poster on any forum successfully using a AW55-51SN where a AW55-50SN was previously fitted.

If anyone can point the OP to a thread where this has been done he would at least have a reliable reference source.

Also you can't rock up at a dealer with your 2004 transmission and ask for 2004 TCM firmware. The main engine computer's firmware will not accept the 2004 firmware as version numbers need to match and be compatible.

Send it back.
