Transmissions, commonly involve principles similar to that of a PTO, albiet within the same mechanism (usualy a 2-speed drivetrain).
One pneumatic actuator pushes a set of gears between two settings, causing the mesh between the gears to be modified.

DO NOT use industrial lubricants like WD-40 or white lithium grease on internal plastic gears inside V5 motors or cartridges.

You may use light synthetic oil or synthetic grease like SW-92SA that is used for fine/plastic mechanical internals of cameras, printers, keyboards, dvd players, etc…
