722.6 transmission question

Do all 722.6 5 spd automatics share the same transmission housing and bell housing bolt pattern?

Besides the internals....does a 722.6 that came from a V6, V8 and V12 can bolt up to a different engine? Like say a CL55 transmission bolting up to a V12. I know with other manufactures the bell housing was different to deal with the different V angles. Such as a 90 degree V8 and a 60 degree V6. But looking at the 722.6 the pattern to the bell housing is pratically a circle so not sure if Mercedes did the samething.
Can anyone verify this? Thanks

P.S. I want to use a CL55 transmission on my M120 V12 project since that transmission would be considered an upgrade.

Swapping bellhousings on any trans will require setting up the "height" of the gear train with shims.

Not sure what you mean by that? I was curious if they share the same bell housing and bolt pattern.

There are many different types of 722.6 gearboxes. Not all are compatible with each engine, some are stronger than others.
