Nevermind. I found the info I needed. Go figure, I've been looking for several days (about 30-60 minutes each time). Then 10 minutes after making this post, I find a perfect explanation.
In case anybody is interested, this link has a step by step instructions with pictures on how to separate the M4 and also what is needed to get the gearbox out.
