To check level of trasmission
Transmission on 2007 Mercedes-Benz S550
The transmission isn't exactly a "sealed unit". But, special tools are needed to fill and set the level of the transmission fluid. I recommend having a Mercedes-Benz dealership do this for you to ensure the proper fluid is used and the fluid level is set correctly.
