Automatic transmissions ensure that the engine always runs in the ideal efficiency range. However, as the complexity of transmission control increases by increasing the number of gear steps to 5 to 9 gears, the performance requirements of the transmission also rise. This is noticeable in the enormous thermal and mechanical stress on the transmission oil. The consequence: increased wear and thus increased maintenance requirements.
If the transmission oil is not replaced in time, the dirt and metal abrasion it contains can cause costly mechanical damage to the shift box. For this reason, their manufacturers and also more and more vehicle builders are making recommendations for changing the transmission oil, depending on driving performance and driving style. This also applies to so-called "lifetime fillings".
In the past, however, it was not possible to completely replace the lubricant, which meant that when the transmission oil was changed, contamination of the fresh oil with the remaining used oil was inevitable - a problem that is now a thing of the past thanks to LIQUI MOLY. This is because the in-house automatic transmission oil service unit enables almost 100 percent fluid exchange without mixing fresh and used oil. Only then can the new oil develop its full performance.
optimized shifting behavior
Any shifting delays, unclean shifting processes or even the failure of entire gears are eliminated and lead to optimized smooth running.
increased service life due to reduced wear
Reduced friction due to the removal of deposits and dirt ensures less wear and tear and thus a longer service life of the transmission.
lower fuel consumption
Early and soft shifting times have a positive effect on fuel consumption.
