Transmission fluid and filter change
I am trying to find out if its time to do a automatic Tranny and filter change. I bought the X3 2005 at about 70,000 km pre owned. After a lot of highway travels I now have 140,000 km. Since buying the car I have not done any transmission fluid or filter changes. No real tranny problems other than the the fact that as with age most auto trannies get sluggish.. In any case, could ppl chime in here on their experience with changing the tranny fluid and filter and what I might expect in terms of performance improvements etc. Approximate costs would help as well. Thanks.
