Automatic Transmission Fluid
Be cautious when dealing with transmission fluid. Dispose of the drained fluid properly. Bear in mind that: One drop can contaminate 1000 liters of drinking water.
Transmission fluid does not just "lubricate" the transmission.
Imagine: The fluid also transports the finest differential abrasive particles in the filter, ensures the lubricating film does not wear off the differential tooth flanks and at the same time, it acts as a switch valve pressure medium to enable it to perform its functions.
It also seals the selector lever and helps clutch friction lamellae (plate) when shifting gears. It conserves and transports warmth, minimizes noise - transmission fluid has many tasks. And it does not matter if all of this takes place in the heat of the equator or in the cold of earth's arctic poles. Transmission fluid meets some very high demands.
Transmission Fluid Troubleshooting Check
You have already read what transmission fluid can do. Now for something it cannot do: >>Disappear without a trace.<<
Transmission fluid can only be missing if it has leaked from the transmission.
-- on where it has escaped from the transmission. Repair this leak first.
Transmission fluid is a permanent fill. As far as Maintenance is concerned, the transmission does not need to be replaced.
The transmission fluid level inside the planetary gear and inside the final drive are checked and filled at the same time. Refer to TRANSMISSION FLUID LEVEL, CHECKING AND FILLING .
Do not mix any additives with the transmission fluid, do not add other transmission fluid types.
Drained transmission fluid must not be reused again.
