Even after you clean it, the O-ring of the OEM CSC will still deteriorate. I sent Joe the failed OEM CSC for additional analysis. Maybe you can try to rebuild it with new seals.

The first HD-CSC was fine, but there was a thick layer of soot due to clutch disc burning up from rubbing against the flywheel. It was gross, so it necessitated replacement. I went ahead and ordered a new master (first one already failed in Houston after getting the new turbos and clutch kit installed) and HD-CSC. The new transmission had 5th gear issues after a month so they ordered a new one. I figured the new one didn't have much miles so it didn't need replacement.
