why does my mercedes ml350 2006 always jump

Sounds,to me like trainsmmission problem,check fluid level,and that is good ,go have trans. checked out.

I don't think that silly Mercedes will have an easy way to check the fluid TopShade. I don't know how sure of themselves Mercedes was in 1968. Do what TopShadeTree says if you can find a dip-stick. Otherwise;skip step 1 and go to step 2.

thank you I thought so too and that sounds expensive.

and again- just the Anne Landers in me---make sure you find a reputable shop and get a written quote before you let them in your wallet.

probably, but that's your decision on what your baby is worth to you,I also would normally say get 2 or 3 estimates but on your car you may not have too many places that can work on it (or will). My bad I saw 1968 after your name and not the 2006 before Mercedes ;so, I think you can go to step 2.
