Anybody out there know how to convert a 1500 silverado 4x4 into an AWD like the SS, C3, or denalis? Thanks

 

Leave it in 4HI?

haha jk...

can you explain a litte more?

 

what else needs to be explained? and I believe it would just take a new transfer case and prob a tune of some sort, that should be it.

 

I was told you needed some sort of control module or something when I looked into it. While everyone told me it was completely mechanical- it is computer controlled.

 

i think you need the AutoTrac (or whatever its called) transfer case. basically one out of an SS or other truck using AWD. and yeah you'd probably need a tune of some sort.

maybe go over to silveradoss.com and ask them?

 

i'm not 100% positive but i believe the front diff is different, dont really see why it would be but i've heard it was

 

You need the transfer case and front diff from a Escalade, Denali, or Silverado SS. The Autotrac version won't work because it requires input from speed sensors to engage the front clutches and the front diff is a part time design.
My NP8 transfer case doesn't have any electronic interface, it is strictly mechanical. Not sure how it works, maybe torque sensing clutches?

 

The front differential is different between the AWD and 4wd trucks, the AWD has a one piece axel, without the engagement solenoid. The transfercase in the C3's, SS's and early model Escalades and Yukon Denali's are NVG 149's, which are mechanical with a viscous coupling. The later model Escalades and Yukon Denali's use a Borg Warner transfer case that works as a center differential in conjunction with the traction control "which may be why you were told you would need contoller to make work". The NVG 149 would surely be the one to use.

 

So how do the newer transfer case and traction control work together?
Do the NVG 149 cases have any electrical control?

 

Wheel spin is controlled via the traction control on the BW units, as they operate as an open differential. The NVG 149's are totally mechanical in nature, with a normal 38/62 split, but can go as much as 100% towards the axel with the most traction as needed.
