RS6 US VIN Compilation.....

[SCARGO]

Sure enough, no transmission or TC issues until I join the forum and then... codes.
Potentially an interesting data point for the early vs. late VIN threshold debate as well.
905090 with a build date of July 2003
TC code came up and the TC was just out of spec and starting to slip causing an intermittent code.
Replaced at 106,738 for the first time. Very fortunately covered by the extended power train warranty I purchased. Replaced the valve cover gaskets as well- also covered by the warranty.
Upgraded to the Bufkin pipe as long as the engine was out. Thanks for the suggestion!
Transmission appears to be going strong. (knocking on wood...knocking on wood...)
