    Ah, the wonderful world of automatic transmissions. I had the same problem in my 1992 535i (in bmw heaven now). I was told that I needed a new tranny from a tranny shop, so I got one. Then the same problem happened on the re-built unit! Then I took it to my mechanic (which I should have in the first place), and the problem was a $25 TRANSMISSION SWITCH. Have that checked out on your E31. Hope this helps.
