If this oil is filtered with a Full Flow filter, it should clean as normal. No affect on the operation of the gear box, except to clean it with the motor. I forgot to add that Auto-Rx is an excellent cleaner for gears. It is used in industrial applications in the gear boxes, printing presses is one that I know of. It is the same exact product that goes in your auto engine.
