You can get this stuff over the counter at any Ford dealer. Have no idea what the makeup of this stuff is but it works. Goes for like $8 for the bottle which is like 6 or 8 oz's. Not sure if its compatable with the synthetic gear oil, you may want to check that out first as I have only used it with coventional gear lube.
