Transmission Fluid Change (ATF) [PLEASE READ ASAP]

[TheKingSim0n]

Im at 116,500K with my 4.4i, Ive been noticing a bit of slipping with my transmission when i drive on the highway for about an hour or so? I went to my uncle's shop out here in BK and he told me to come in tomorrow & he will look and change the ATF (Auto Trans Fluid). My question to my fellow X5 owners is, whats the best fluid to use for a 4.4 01?

And please don't reply with that BS that BMW says that ATF on X5s is a lifetime fluid, its not..... point blank after 100K all cars need to be changed at least once.

Thank you! =)
