I've been reading all kinds of stuff about not only when you should change the ATF to articles stating its a sealed system so no need to change. I have a 98 328 with 80,000 miles. Mostly highway driving, dont race but it has been shifting a little rough between second and third. Not enough that anyone in the car notices but I do-of course.
I can't believe that these things have life-time oil, so when do I change?
