Transfer Case

[Jermoslin]

Selling an Autotrac 4wd transfer case out of my 01 1500 Z71. Removed because I converted the truck to two wheel drive. Comes with harness and if you want control module and push button switch from dash. $500 OBO. Need to pay for the 4L65 I built.

If I were to convert to Auto-trac instead of my T-case so I could do 4wd launches can I use this on my 06 even though its older?

Aggie if you have a manual shift TC there is a lot to make this NP8 (apparently) work. You need the TCCM, the wiring harness (either spliced in or a new complete harness for an NP8 set up) as well as a tune that will recognize the NP8. There is no benefit in a racing application to this swap although this TC is a neato piece and an OK deal. You can pull a lever from 4HI to 2HI as easy as you can push a button and with the manual lever you know it moves to 2HI whereas an NP8 has to do it electrically. The NP8 does have the AUTO setting but that's more of a front/rear posi for ice, snow, mud, rain. This is a good deal but it's more in line for someone that needs another NP8, not really a swap from something else deal unless you are industrious.

Then again, if this is not an NP8 then the OP needs to edit and so do I

NP8 like I thought. Takes a lot of work to swap this in place of the manual shift T/C.

[Faze2183]

how many miles are on it? been abused much?

[GasGuzzler]

Bump

[AKlowriderZ71]

Bump for a good deal, these things are over $1200 new at the dealer, and that might even be a reman, I don't remember.

[Jermoslin]

100,000 just pulled it out last week to install my built 4L65E that I converted from my truck. No problems at all with it.

[GasGuzzler]

At least you don't have to walk far to punch your warranty RO's.

TTT for a good deal.
