Need a little more to go on, Like the exact model there is 22 different models of the M9540!
Edit:
Looks like they are all about the same.
Here are the pictures of the 2 block types and the 2 valve types, they both use the same ports.
Looks like the return goes to a plugged hole in the right side of the transmission case, the second to last fitting is just a tee with a cap on the bottom, so it might be a drain plug that it's ported to.
