Hi,
Okay, it sounds like the problem is the transfer case and not the transmission. There are two different transfer cases used. The NV231 and the NV241 were used.
On the side facing the rear of the vehicle, there should be a round steel label identifying the transfer case model. Could you check that and let me know which one you have?
Also, let me know if the transfer case fluid is clean and full.
Take care,
Joe
