This is good news. I started with the project to change all fluids, have only completed the rear diff. I was worried about the TC throwing a code after I changed the fluid, since our '07 328xi wagon is the wife's DD. I called another local dealer, and they don't recommend changing fluids, and of course the SA does not know if anything has to be reset after the TC fluid is changed. The nearest dealer wants $505 labor to change the trans fluid alone, and the dealer I called today recommends not changing it, and they "suck" out the old fluid. I have all the parts, I'm dropping the pan and replacing the filter.
I plan to follow the advice of Bossimo and let the car go to sleep before I do the TC.
