OK I did transmission fluid flush on my 02 4.4i

Again, this is supposed to be a discussion and so far, its one sided.

But you'll probably come back and say "I don't need to provide proof" Well, thats fine. Our proof is from members that have explained the situation in detail. Also from techs explaining it in great detail (BMW techs and indy's). So sounds like this thread is dead. You want to provide YOUR proof, we welcome it. If not, then I guess your information is heresay, much like ours.

I probably shouldn't have waded back in again

I provided the links immediately above for the reading pleasure of newer members who might not have seen this particular debate before. It is all the same information as this time around.

I was also told last time around that the burden of proof was all on me with respect to the claim that properly done automatic transmission fluid changes on healthy transmissions can precipitate failures due to the detergent levels cleaning out the transmission, and shifting the resulting sediment into the valve body, causing shifting problems. My anecdotes, combined with the anecdotes of two forum members who were BMW technicians, and others in the business, didn't weigh up to the trusted independent that does Sunny's work. We couldn't help Sunny in this case, but there was a large offline discussion going on at the same time, just discussing that particular thread. It was, as my daughter would say, epic. It is the third one in my post above.

I also asked about a particular claim that Sunny made, namely that no fluid is lifetime and by inference, that old fluid was contributing to transmission failures. There was no proof provided for that claim. Using the same logic (one would think that would be logical, burden of proof and all....) I asked Sunny for his proof. He said it was a fact, he didn't need to prove it. That's in the third link as well, post #177. Oh well.
