My 528i is in it's 14th year and is now wearing over 145,000 miles. Everything works perfectly, and a recent investigative emissions test reveals that CO and HC are at ridiculously low levels etc.
However, I have never been near the transmission. BMW says sealed for life. Hmmmmm....... the life of what? The car or just the transmission?
BMW advises against replacing the fluid but many people agree that it doesn't hurt to have it replaced.
There are no particular problems with the gearbox other than the occasional slightly firm downshift from 5-4 or 5-2 under full bore kickdown. I am not sure that the shift quality has deteriorated but then gradual degradation is often not noticed.
So, I have to decide whether to get the ATF (which is some synthetic Dexron III/IV/V derivative) drained and replaced? Cost is approximately £200 but my fear is that if it's not done correctly I could destroy the gearbox in short order.
Anyone any ideas/suggestions? Any recommendations as to whom I should engage to perform this task? I don't mind travelling to get the job done properly.
Thanks in advance folks.
