I am in the process of gathering parts for a 4L80E swap into my AWD vehicle that originally comes with a BW4481. The BW4481 is a one range 0 input tcase.

I have considered the 149 viscous clutch but I don't like the idea of a lifespan on the tcase and it is really meant for very limited duty cycle. Plus it looks like the conversion input shafts are pretty rare.


I have purchased a NP261C on the cheap from a local and almost have the transmission. (Considered a NVG4500 swap but the cost is crazy $$$$$)

Anyways I heard about the BW4482 that TURBHOE runs. This is an AWD transfer case that LOCKS when you put it into LOW RANGE. This is exactly what I want but it is electronically shifted.

I have no idea how do do the electronics. Do you need a specific OS on the computer to do that. What all is involved and what would need to be purchased.


I think the N261C would be EASY and work great but retaining AWD sounds like you run into less of a chance of getting stuck in the first place but 4WD when you need it. The other thing is that AWD also might help me skip upgrading the rear end.

The only catch is that I would still need to find an input shaft or a conversion piece. It doesn't look like a readily available part.
