I have a 2008 mini Cooper Clubman S with 220,000 miles on it. I have started having problems with the Aisin 6 speed automatic transmission reving as it shifts between 3rd and 4th gear. While I'm looking at the possibility of replacing the valve body I am also looking at possibly getting a used transmission. Question, can a newer Aisin 6 speed automatic transmission of a 2011-2013 MINI be used to replace a 2008 model automatic transmission? I believe they are the same transmission from 2008 through 2013 but there may be coding issues or slight differences. Please let me know.
Why is the dealer the absolute last resource people turn to with these cars? I'm sure they can tell you whether there is a software issue, I know of no hardware incompatibility......
It's possible you might need the dealer to update the software depending on the year of the transmission you find. I think this is a good idea for a high mileage car actually, and the direction I'll go if I need to with mine.
A visit to your dealer might give you everything you need to know before you go hunting for the parts......
