Hi all... regarding these 4.8is posts from a few years back now... my 4.8is Dec 2004 V8 (facelift) 6 speed auto has now covered 110K miles. I would like to do the transmission fluid change. Lots on that here thankfully. What fluid is best or would you just go with BMW dealer advisory? also vehicle still changes gear smooth and fine (for the main part)...... just occasionally it revs high in 1st and pretty bloomin' harsh change into second (changes late & hard) ... but only occasionally....... any ideas on this? Thanks for any advice... with thanks malc.
