so bmw says tranny fluid is life time. i dunno, how would u feel if bmw starts to say engine oil is life time? or brake fluid?

to flush or not to flush? also i heard that some people say the dealer actually doesn't flush all the fluid. just 50% or something like that. hmmm... a flush job is $500 so i wonder if i should do it or not. my 09 30i has 60,000kms.
