I can't seem to find any threads on the topic.
I have M54 3.0 automatic and I want to swap to 8 speed tranny like pazi. He has M57 diesel but those are impossible to find in Canada AFAIK.
So I want to swap both engine and transmission.

There are lots E53 V8 4.4, 4.6 and 4.8.
I've done too much to my E53, so I don't want to sell my i6 and buy v8

I really wanna do a swap, but not finding lots of fresh info on E53
