Here's a tip, whether or not you chose to modify the gearbox. We found in years past that cleaning the stock grease from our NBD gearboxes and using light lithium grease had a noticeable improvement in output (efficiency). It looks like this gearbox is pretty clean - don't know if it was that way when you opened it, but even if it was well lubed it might be a good idea to clean it out and put in lithium grease. (which per update 5 is an allowable material).
