BG Transmission service

recap from previous threads!!!!

So I'm at the point when I need to service my SMG transmission, took it to the dealer and they keep telling me "lifetime fluid BS"

So finally got over the phone with BMW USA, and they said that same things, but mentioned that if the SMG fluid is serviced, it will need to have the software updated. Took it to a few indy places and they say they can do the service, but all of them work with non-OEM fluid, and after mentioning software they were like......whoa....whoa.... that we can't do.

Finally found a shop that have the equipment to update the software and they were great talking about SMG, so it seems they know what to do, but they mentioned that they only give warranty if the service is performed with BG Transmission fluid, and that in fact the specs were better than OEM.

Any thoughts??

Is SMG fluid that special or BG fluid will be same/better??
Should we just replace the fluid or flush and replace??

Any other details you know or can share with me will be welcomed, thanks
