Automatic transmissions require a special service. Whether it’s a combustion engine, hybrid or electric vehicle. The ADAC motor club recommends an automatic oil change every 100,000 km at the latest. Modern automatic transmissions and automated manual transmissions always keep the engine in the optimum efficiency range.

As the complexity of the transmissions increases, together with more and more stages and up to 10 speeds as well as additional modes (comfort/sport/winter), the demands placed on the transmission also rise. The gear oil is subjected to enormous thermal and mechanical loads.

Regular professional transmission service and timely gear oil changes are essential. Otherwise, the dirt and metal abrasion contained in the oil can cause expensive damage.

If the transmission fluid is not changed in time, the dirt and metal abrasion it contains can cause costly mechanical damage to the shifting mechanism. This is why the manufacturers and an increasing number of automotive engineers are issuing recommendations for changing the transmission fluid depending on mileage and driving style. This also applies to so-called “lifetime fillings”.

However, a complete change of the lubricant was not possible previously, so that contamination of the fresh oil with the remaining used oil was inevitable when the transmission fluid was changed – a problem that is now a thing of the past, thanks to Gear Tronic III. This is because the automatic transmission fluid service unit enables an almost 100 percent fluid exchange without mixing new and used oil. Only in this way can the new oil develop its full potential.

Another advantage: Thanks to its automated processes, Gear Tronic III avoids costly errors and possible over- or underfilling. The unit is thus the perfect all-round solution with which purging, transmission fluid change and the addition of additives can be carried out easily, quickly and safely.
