hey all , i have a mercedes 350sdl. it has lot of miles on it (over 175k) but it still runs well. Today I noticed something odd. When I would accelerate above 40/45mph, i would hear a hissing sound, sort of like air hissing out of a leak. Also the acceleration wasnt working correctly, I could barely get above 50mph - the rpm was spinning up but the car wasnt accelerating like it should.
I took it to the mechanic who knows the car well, and he found I had very low tranmission fluid. We filled that up and I did some test driving in the city around his shop, and it ran normally - I was very pleased. He told me if it went back to the same probably there might be a fluid leak.
But when I got onto the highway to go home, my acceleration felt not as strong as it should when going for exapmle 50-70mph. It was fine going from stop to go, however.
Any ideas? and I still don't know what that hissing sound from earlier was.. but I haven't heard it since,
Thanks.
