L76 4l70e swap, need transfer case help
I'll be swapping a 2008 l76 and 4l70e into my grand wagoneer and need some help picking a transfer case. I want to go awd, from what I can find it appears a nvg-149 would bolt right up to the output shaft, I think it's a 27 spline on the transmisison and the 149 takes the same.
So I have a couple questions:
Am I correct and if so, what should I be looking for one to be pulled off, a 2003 Denali?
Is the 149 a good choice for the L76 vortec max with a black bear tune or are there other suggestions? I want to stay away from anything electronic that would require sensor readings.
With the 4l70e, is the speed reading wired to the transfer case or the transfer case? If the t/c, does the 149 have a speed output that will connect up with my harness?
I won't have the drivetrain for another 2 weeks so can't look to confirm and want to have everything on hand as early as possible. Any help is highly appreciated, I have been unable to get any locally. I realize there's likely more I am not considering, this is my first swap and really any major dealings with the transmission and transfer case workings.
Cheers
James

Thanks for the help guys! I think I have it honed down to the vehicles to select from.
Do you happen to know, are the splines the same in each of these years (01-02 Gmc Denali SUV or a 01-06 Denali truck, 03-05 Silverado SS), so if my transmission is a 27 spline then I just need to grand any of those that I can get my hands on? Are there any you know for sure that are a 27 spline? I think I found that the SS's are, curious about the others.
