If I get a ZF6, will I be able to keep my NP273 transfer case? Or will I need to get the one that comes with the ZF?

 

The V10 has a np273 with a has a 31 spline input , You need to swap the input shaft to a 34 spline to mate to the zf6 output . A new input gear is about $100

I think the 6.0 equipped trucks with the 5r100 trans had the 34 spline input np273 if you want to swap the whole case.

Obviously you will want to verify this, been awhile since I considered doing it.

 

I want a ZF6 in my Excursion soooo bad, or even the 5 speed.

 

Here you go- I think it would be great, at least for a week or so.
