Have a 22 Chevy duramax 36,000 miles. Had it at dealer for warranty work on def tank heater. They noticed trans had a little oil leak on it. Said there was an update in gaskets , They asked if I wanted the updated seal kit as it was still under warranty. I gave the go ahead , but it was in the shop for about 3 weeks waiting on different parts to show up
