This is my first post, my apology if I am in the wrong place.
I need help to identify the transmission/t-case in this picture, I thing is W56 and I don't know if is Top or forward shift.

I find out this is W59 from a 3RZ. This trany will be direct bolt my IFS to replace the G52?
Thank for your input.
