3B tranny same as MC-2 tranny?

[Shayne]

Hi-

If I read the post right, you have it backwards.  The 4.11 will cause higher
RPM's.  BTW, as you probably know, from an external standpoint, both trannys
are nearly identical.  I bought a brand new one of each.  Compared them side
by side.  The only big diffs where a couple of changed sensor locations (or
deletes) and I think the ADZ (3B) had some added cooling fins.
