4L80E swap with US SHIFT trans controller for 4X4. anyone done it?

[Nasty-LSX]

I really think its time to swap out the 3L80 (TH400). I love driving this truck but the 3 speed trans GOT TO GO!!!
I am going to build one of my famous 4L80E trans for my 85 K20 4x4. I would Like to know if anyone has done this
and made the controller work with the transfer case. I will also call usshift.com tomorrow and see what they say.
If they say it works, Then its a go for me.

Haven't done it with a t-case, but just did it in a 2wd car. Here's the settings available for transfer cases. There are extra settings in other areas, such as TCC Commander for 4 wheeling.

Thanks Tonimus. I seen that. My concern is I never seen a 208 T/C with a factory VSS. some how some way the 208 would need to be converted. I would like to know if this is possible and how.

If you use a controller that doesn't control line pressure also do transgo 48mod or youll be running full line pressure at all times. So it's 48 mod or modify the pump or it will cause damage.

Ok, just got off the phone with usshift.com I will be picking up the quick 4. it does it all for full control
and I dont need a VSS for the T/C. it only runs on the input out speed sensor sets. (transmission only)
and I keep the speedo from T/C. All gears work in and out of shifting T/C. Thats pretty cool. I will start a
build thread on this.
