Man, that was just plain painful to try to read. Please use punctuation, correct spelling, and paragraphs. People are more likely to respond to your question if it is easy for them to understand.

 

Along with the above, please use the search function. There are plenty of in-depth discussions about the NP8 - NV236 transfer case. You can start your diagnosis by getting the TCCM scanned. Only a Tech 2 or equivalent full feature scan tool can scan the serial bus communication devices such as the TCCM.
