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.

Hi, the transmission is a sealed unit, I recommend transmission pros. Try L&M transmission in Paterson 973-279-0600
