Information sites and vehicle specific numbers
Not sure if any of these have been posted before or not. Just some transmission/transfer case information and supporting sites that I have found.
Hopefully all who are gear heads can add to this or correct what is incorrect and gear heads/non-gear heads can find some useful information.
