The use of modern automatic transmissions and semi-automatic transmissions in vehicles is becoming increasingly common. They ensure that the engine always runs within an ideal range of efficiency. However, the increasing complexity of the transmission control introduced by increasing the gear shifts from 5 to 9 and extending the transmission steps with Comfort, Sport, Winter and so on has also increased the performance demands made on the transmission. This in turn is noticeable due to the huge thermal and mechanical demands placed on the transmission fluid.

The result is an increase in wear and tear and therefore an increase in maintenance requirements.


If the transmission fluid is not changed in good time, the dirt and metallic abraded matter could cause costly mechanical damage in the gearbox. That’s why manufacturers of transmission fluids – and increasingly vehicle manufacturers as well – recommend transmission fluid changes, depending on mileage and driving style. The same applies for so-called “lifetime fluids”.

Previously, it simply wasn’t possible to effect a complete change in lubrication, since it was inevitable that the new fluid was contaminated with the remains of the old fluid – a problem that is now history thanks to Gear Tronic II. That’s because the automatic transmission fluid service device allows the fluid to be replaced virtually 100 percent without the new fluid mixing with the old. It’s the only way to ensure that the new fluid is able to work to its full performance. A further advantage is that because it uses automatic processes, Gear Tronic II stops expensive mistakes from happening and prevents overfills or underfills.


The device is therefore the perfect all-round solution for flushing, carrying out transmission fluid changes and adding additives – easily, quickly and reliably.

Many good reasons to choose Gear Tronic II



  • Color display including inlet and outlet pressure display and temperature measurement of the gear oil.

  • Cleaning additive can be connected to the device directly from our 1l can.

  • Automatic flow direction detection (forward / reverse).

  • All data is entered via the menu before use: Vehicle manufacturer, vehicle type, motorization The database plays out further data: - Total fill quantity of the automatic transmission, automatic transmission oil type and density, tightening torques of the oil pan as well as the drain and control screws.

  • Documentation of data via integrated printer.

  • The database is updated directly to the device using a USB stick.

  • Remote maintenance of the device by LIQUI MOLY application technicians. With remote access, functional tests can also be carried out abroad without great effort.

Well-tried properties in our new device:


  • Flushing of the gearbox and oil change via dipstick guide tube, gearbox oil connections directly on the gearbox or gearbox oil cooler possible.

  • High accuracy in fluid exchange thanks to two independent and high-precision scales in the device.

  • After the oil change, less than 100 ml remain in the device.

  • Very simple menu navigation in different languages ​​and fully automatic system flushing operation.

  • Easy connection to the vehicle transmission oil system thanks to universal and vehicle-specific adapters.

  • Protection of the vehicle in the event of a power cut thanks to the patented bypass circuit.

  • All connections are equipped with check valves.

  • High pump performance with up to 10l / min.
