I am looking for Nissan Pick-Up Manual 2001

hello friends,

I need your help to find a mechanical workshop manual with its respective diagram of parts of the entire car or transmission, the vehicle is:

Nissan pick-up (truck although also called truck)
Extralarga version -longest back -
2001 model -almost all of them are similar-
5 speed transmission

I would thank you if they could facilitate a manual or the pagan where to get it, it seems impossible I have been looking for and I do not find some useful.

-The manuals are also called (patents, mechanics manuals, parts scheme, mechanical diagram, maintenance diagram)

Here is a photo of the truck (very common in Mexico)



Here is an example of what I am looking for:



(This is an impact key, but I look for one of the transmission of this truck)


I thank you for your help
