The problem with this is if the transmission were to have problems because the fluid went bad it'd likely happen after the warranty in which case you're screwed. But if you do it before the warranty expires you're no longer protected under the warranty for any other problems. BMW won't stand by its warranty if its own dealership technicians perform the change? WTF?
The pans are plastic & are known to warp & leak requiring a new gasket at the least. I recently had mine replaced as well as the linkage sleeve. Quite a few members here are reporting the same issues ....... some having the pan replaced altogether.
