Hey everyone I may have potentially found a new cure to SMG problems. My 2002 LSB M3 was dropping out of gear while driving, and going back in 5 seconds later. I took it to the dealer, and two other shops, and they diagnosed it as the pump. However, I refused to believe that because it was shifting perfectly (when it wasn't going out of gear), and it was priming just fine. So after A lot of research and reading numerous threads, I came across a few that mentioned the temperature sensor on the SMG unit possibly malfunctioning. However, I did not find anyone who actually attempted a replacement. So, I did. I ordered the part, took it to a local shop, and replaced it. Also, I lost some fluid, so we added some fresh Pentosin, primed the system, and so far, I am 200 miles trouble free. I am continuing to drive it to test this fix, so stay tuned. The part number is 13-62-1-709-966 Lets refer to this fix as the MOZE fix (my initials) lol.
