It looks close, double check that your PS lines will connect and you can get a wrench on them with it installed so close to the frame.
It does look like you will have plenty of room for the transmission.
I have had mine mounted in two different trucks about like you have yours mocked up. If I do it again I would try to mount it farther back to make it less cluttered beside the transmission, but then again I was not worried with a transfer case possibly being in the way?
