Re: WK2 Transfer Case SWAP

There is a transfer case control module under the driver's seat that you may need. There is also a AWD driveline control module somewhere, but that may only be needed for the QDII ELSD.

Dunno if there is a difference in the software on the Powertrain Control Module (PCM) or the Transmission Control Module (TCM). Dunno if the ABS controller is different.

Re: WK2 Transfer Case SWAP

Below is a link to a 2010 WK discussion, I would think a WK2 swap would be at least as difficult except I think the axle ratios are the same on the WK2.. I'm speculating here, you may just want to wait until someone drops into this thread that has done it. A google search found nuthin else as far as I can tell.

Re: WK2 Transfer Case SWAP

I have QTI and considered this myself, but put a swap out of your mind unless you've attempted this with other vehicles before and swaped in engines, t-cases, etc.

Better to just suck it up and keep it (which is what I did), or trade it in for what you should have gotten in the first place (which is what I will do).

With that said, QT1 is a fine system, and better than previous QT1's from what I can find, much smarter and more capable system than early QT1's. I've never "actually" used mine and failed, but there are times I've said, "I wish I had 4-lo so I'd be more confident in doing xyz," as I would probably attempt more if I had 4-lo.

I could be wrong but I think the TCM/PCM would need to be programmed for having the different datasets to be able to use the select-terain settings (and to know how to enable 4-low). However this stuff might already be in the programming and if it doesn't sense a select terain module it may run the a default paramter set for QT1. I'm not a chrysler engineer but sometimes its easier to program everything so that is it plug and play from the factory. The less input needed by the line worker the more reliable the vehicle will be that it starts when it reaches the end of the line.

THEORY Example:
PCM default mode is QT1, this set will run if select terrain, is not awake on the system.
PCM subset 1: a set of parameters and shift settings are enabled becuase it detects select terrain and does not detect Air suspension module.
PCM subset 2: a set of parameters and shift settings are enable because it detects select terrain and Air suspension moduel.

NOW THIS IS ONLY A THEORY.

Realize that what you are trying to accomplish may slightly affect your warranty.

Re: WK2 Transfer Case SWAP

Its good warranty is up in like 4 or 5 months. And yes i have done motor swaps transfer case swaps etc. And am fully capable of doing the grunt work. Including some fab if i need to. and from everything i see the qt II will bolt directly in, im just worried about all the electrical module that i might need.

What type of transmission you got?

This is not just a simple switch. The Tcm/PCM/ECM control how the tcase works. Trade it in.
