yeah man i'm gonna have to agree with you with the oil change thing, If you remember one of the other threads where someone actually took oil to a lab and got it read and everything, BMW's oil change intervals are not that bad. Oil actually has to build up a layer of protection and that takes time and use. I will definitely recommend a fluid drain and fill along with a tranny fluid filter up around 100k.
Great stuff you have here man. I was trying to put it all together in my head. but it seems like the only way for me to know how to do this or even start, is to get a bad tranny and take it apart and try and put it back together.
Thanks neil for this thread. Great photos too btw.
