Gearbox 6hp26 from 550i to 750i

Hi,

My gearbox is in not good condition, probably clutch E is cracked. I have opportunity for getting gearbox from 550i.
Wondering if that could match after mechatronic replacement.

550i has manual switch R/D/N, 750i electronically, that's my concern.

Thanks in advance for some suggestions.
