I have a 2015 ML250. Transmission feels like it is starting to slip a bit, so I want to check the fluid. I cannot find a dipstick. I have no indication on the instrument panel that the fluid is low, but I don't trust that. Thoughts??

 

when i originally asked dealer on my 2016 gle 350 they said no dipstick; need to go straight to trans. i therefore leave it yup to them on services. good luck, ron

 

If the filling procedure is like the ml350 it needs to be filled from the bottom of the transmission with a pump and a hose connected to the drain plug. There should be a youtube video about filling the transmission on your ml250. Its not as easy as one would think. Good luck
