Transfer Case?

[afgunn]

1) Can someone tell me what transfer case I have based on my sig below? And how I may verify that. I have the RPO Code: NP1 Electronic transfer case.

2) Based on the transfer case I have, will it bolt to an Allison 1000? If not, then what transfer case do I need to get for an Allison?

Thanks guys!

I suspect you have a NV246 case in it. I could be wrong on that though.

The Allison gets backed up with a NV 263XHD case. Its a very heavy duty unit. The XHD suffix gives it heavier input bearing and a few other upgrades.

OK, thanks. I checked online with the info you gave and confirmed that my truck does have the NVG246. I will crawl under the truck the first chance I get and make a positive ID! Thanks again, very helpful!
