Just as an add-on. When looking in the maintenance manual for grease with the required Molly percentage I couldn't find one, there is a grease with Molly infused but not at the percentage Mooney requires. So, I asked myself, that requirement was back in 1965 (I have a 65E with electric gear) and greases have changed over the decades so do I ignore the percentage difference? It's not that much more. Then I looked up Molly, what it does, and how it applies to Mooney. This is what I learned. The reason why Molly is used is to fill in the areas between the gear teeth. It's also used to reduce the wear of the gears. The grease with Molly is used in a high-pressure environment, like the sudden pressure placed on the gears when you select up or down. So, understanding the reason why Mooney wants a certain percentage of Molly/grease in that area, do you accept the off-the-shelf product or mix your own? If you mix your own, you have to now consider which particle size to use, the fine or coarse.
Just a bit more to consider when talking about those two tiny little gears and what you are asking of them perhaps thousands of times!
