7AT VLSD fit MT Diff housing?

Spencer@Z1

You can interchange housings. As long as you are changing all of it.

You cannot swap differential units between the MT and AT though due to the offset. I believe it is .4" difference in offset from the MT to the AT viscous where the ring gear bolts.
For instance if you try to use an automatic viscous with a 3.69 gear it will not mesh the teeth, looking at it from the rear the ring would be .4" too far left.

You can run a 3.538, 3.692, 4.08, 4.36 gear with a manual diff but not with an auto lsd or open diff unit. If you want to upgrade the gear in your auto you will need a "manual lsd" too.

If you want to upgrade the diff only in an auto we have diff options for that but not gear options without changing both. You can do either in your own housing whether it's manual or auto.

Hope this helps.

So it is indeed just the carrier that makes the difference & not the housing, so it would be basically a normal carrier split. Gears 3.538 & lower (numerically higher) = Manual diff, Taller gears need the auto diff. & Either an auto set can be installed in a manual housing, or vice versa. is this correct? I also know the axle stubs are different as well.
Thanks for the insight.
