Micro Polishing is one of the best things you can do to improve your transmission! Micro Polishing very gently polishes and smooths your gears and removes metal stresses uniformly. It gently polishes the gears faces and dogs in the contact zones, reducing friction, and frictional losses. That means less heat, better fuel economy, and longer life. Micro Polishing will not make your gears stronger (just the surface), but reduced friction means reduced stress which equals better durability under demanding conditions!

Less inertia = Less friction = MORE POWER = Less fuel consumed

Reduction of friction of metal to metal contact parts = Less wear and contact fatigue

Lower operating temperatures = Increased power output and efficiency

Increased power density = options of larger engines or smaller transmissions

Increased durability = Lower replacement costs and fewer failures

Improved bending fatigue resistance

Reduced lubrication maintenance

Quieter operation

Reduces rotational torque

No metallurgical degradation

No geometrical degradation


In engines and transmission assemblies, moving parts rarely touch each other. The crankshaft in an engine does not technically contact the main bearing surfaces, only a thin oil film separates the two surfaces. In essence that is in fact what oils designed function, the of use lubricants prevents parts from actually touching. In understanding that... if things don’t touch, where does the friction come from? Take for example transmission gears. As machined from the factory, gear surfaces carry characteristics of fine flaws of very small "peaks and valleys". In the rotation of the moving parts, the gear oil is forced out from between the gear surfaces. As the oil is pushed out, a fine amount of turbulence is created as the oil has to find its way through those "peaks & valleys". This turbulence causes the oil to work in contrast, resulting in friction raising the temperature of the gear oil. 


When it comes to machined parts, smoother is better. However even the most scrutinized machined parts are still plagued by “peaks & valleys” Turned, ground and even lapped surfaces all create some degree of turbulence and increased heat. Standing to reason that any process that removes those peaks will reduce the heat and friction. 


So how is a "peak-free" surface obtained, that doesn't change the size of the parts? Utilizing proprietary technology we can produce a finer quality of work in short spans of time, than others.

We will disassemble the entire transmission, before degreasing and clean every part. The parts will then be Vapor Honed before any polishing will start. We then use a  vibratory tumbler to start the polishing process. Once this step is done we move onto compound polishing. Making sure to hit every surface that will contact with another.
