Hello, I got an 07 4.8i and a 13 xDrive35i as a donor car.

I wonder if anyone has tried swapping in an 8hp transmission to their 4.8. Anyone know if it fits right in? Would be such a pain removing both trannies, transfer cases and what not only to discover that it won't.

I also assume that the TCU won't be compatible with the ECU and other components so I guess I would need a standalone.
