Hello mate, the auto boxes in these cars are generally thought to be strong and reliable. It is unlikely that you will have any issues at such a low mileage if the car has been properly looked after. I don’t have any experience of these ‘boxes directly, but if you search the forum you’ll find lots of good info.
As stated above, if it’s your first foray into E85 ownership, there are other common issues you should be checking out - ABS pump (costly), rear coils (cheap), roof motor fixed/relocated (quite cheap), oil pump housing and valve cover gaskets (common source of oil leaks). Overall though, these cars are robust and easy to look after if you are handy with a spanner.
