Great information but missing 1 washer.
I bought parts to do this a couple of years ago and I'm just getting around to doing it and thought this would help the next guy!
Part number 89059525
on the new input shaft there are 2 Washers that you need to buy.

I just went back and looked, it was the BW 4485 that were in 2007 - 2011 Escalade's.
And these are the parts I ordered to do it.

Part number 15654927 is a transfer case adapter that connects a 4L80E transmission to an NP208 or NP241 transfer case, not a BW4481 / BW4485. Do they line up correctly??
I have a 1968 Chevy C10 sitting on a 2003 AWD Cadillac Escalade with 6.0 LQ9, 4L60E, and BW4481 currently.
I want to swap in a 4x4 4L60E and a BW4485 (or swap 32-spline input into BW4481), but the only place online I've seen anything on an adapter is THIS POST.
If you're still around, I'd REALLY appreciate a response.

I know this is an OLD post, but I am looking to do this exact same thing and curious about that adapter.

Still around and ironically just put the engine back in last weekend, been out for 2.5 years due to losing a rocker arm trunnion and lacking motivation to refresh.
That is the adaptor i purchased by recommendation of a tranny shop, didn't have to make any modifications.
