I really am...I really am.

Your oil change example is not relevant to what we are discussing. I was not talking about tech error (as in stripped drain plug). I was referring to a flawlessly performed ATF fluid and filter change with the proper parts.

I am looking for more than anecdotes. I am looking for something along the lines of:

Out of 100,000 transmissions where the fluid was changed 10,000 of them exhibited a failure. Compare this with 100 (per 100,000) that failed where the fuild was not changed.

How can you deny the sheer number of BMW issues that Mike Miller deals with? He is on a whole nother level than your guy. If he even exists. So far we have seen no proof of this mystery man.


I am basing my information on my mechanic who has 25 years servicing BMW's who states he has observed no increased failures as the result of fluid changes. I am also basing it on the manufacturers recommendation to change it at 100K miles. I am also basing it on my phone calls today to three BMW dealers inquiring into a transmission fluid flush. None of which were reluctant to perform the work. In addition I am partially basing it on both JCL and Mr. Millers statement that the risk is slight (JCLs exact qualifier). And finally I am basing it the complete lack of any supporting evidence. I will remind you the person making a claim ha the burden of proof.
