I have attached 2 pictures of our gearbox (W5A51).
Can some please label these components for me.

From what I know

Red = Output of the gear box that goes into the transfer case .. all of the power front 2 wheels and back 2 wheel goes through this
Yellow = because the front differential is in the transfer case not the gear box .. the is a return power for front left wheel
Green = what is this ? seems like a differential

but according to this video the front differential is in the transfer case
