Mein Auto: 2001 330i
Hello all.

First of all thanks for the great write up Starless.

Second, I have a question. I had my ATF fluid changed by a reputable local indy (Curry's Auto, Falls Church, VA) at 95K miles. They used a trans flush machine, so the pan was not dropped and the filter not changed. They also used BG Universal ATF. Details at http://www.bgprod.com/blendr/syntheticATF.html. I have not been able to find much detail on this fluid.

While researching the issue of idle dipping when changing from Park/Neutral to Reverse/Drive, I ran across the large number of threads reporting reverse failure on the ZF 5HP19, which is what I believe I have. I have a 2001 330i (produced June 2000). And I am becoming partially paranoid about the transmission.

I was contemplating replacing the fluid again with one of the appropriate fluids listed by forum members. I was thinking about draining the fluid from the fill/drain plugs and dropping the pan, replacing the filter, but refilling through the trans cooler lines using a hand operated air pump, in order to replace all of it at once. I have not seen any one on here taking that approach.

I just wanted to run it by everyone else here to get their opinions about what they thought. If not this, then I would have to drop the pan and replace the fluid at least 3 times to get close to all new fluid in there.

Please advise. Thanks in advance.
