99 GMC Yukon: me what transmission and transfer case..correct one

This answer was rated:

After I received my answer I tried asking another related question but apparently it didnt go through.
Anyway I was wondering if Y'all could tell me what transmission and transfer case my 99 GMC Yukon has. I need to know so I can order the correct one for my vehicle so that I can replace it with a working transfer case.
Thanks'
Steve Hoffmann

This is a 1999 GMC Yukon SLT 4x4, 5.7 L v-8 engine

JACUSTOMER-azjtrz8i- :

VIN # XXXXX

GM Tech (Cam) : Ok, you have a 4L60E transmission, and if this has the Auto 4wd , 2wd, and 4lo with 4hi, then it is the NP8 transfercase
JACUSTOMER-azjtrz8i- :

Thanks Cam,

JACUSTOMER-azjtrz8i- :

Sorry its taken so long to get back to ya but I got busy and stuff.
So an NP8 is not the same as an NP241 is it? I was looking online earlier and saw some of them that came out of late '90 series 1500 pick-up trucks.

GM Tech (Cam) :

no, the 241 is a manual case,

JACUSTOMER-azjtrz8i- :

ok that explains that, thanks alot!
