Tranny went on my 2006 s manual at 20k, 3 weeks out of warranty. I brought it in 5 weeks earlier while still under warranty and told them that it was slipping out of gear. They said ?they could not replicate the problem?. I realize now that they chose these words carefully. 5 weeks and 1000 miles later, just our or warranty it blew. Said the tranny fluid was dark and full of shards. Did they not check this last month????? they told me 6k to fix it. I blew a gasket. He called me back a few hours later and said Mini would provide the parts for free if I paid $1300 labor. After researching on the internet, I have found that there are hundreds of people with the same issue on their Mini's, many more then I have seen when I have done searches on other issues. I think this is a huge problem that needs to be addressed.
