What transmission do I have or how do I tell?

[Shonk]

My transmission finally gave out on my 1998 EB 5.4L 4x4 @ 150,000 miles and I need to get a new one or rebuild the one I have. But I dont know what model transmission it is, anyone have a sure fire way to determine the model?

look Hear is a good site to find some info for the tranny...
