yes, the np 246 is the factory autotrac transfer case in a 1500. this is the adapter you need if you're upgrading to a 4L80E and want to use your existing autotrac.

ok that takes care of the bolt on part of it.

but what about the spline shaft size difference??

you need to change the input shaft in the transfer case, there's a very good sticky in the gm section on how to do it.

So just to confirm, I'll need this as part of my 4l70E to 80E swap if I want Autotrac to be functional. :confused:

If so, I'll take it.

TTT, next stop: ebay.

SOLD. Thanks, 356ZUM.
