Hi everybody,

I have w108 280SE 3.5 and recently experienced with some weird sound which comes out somewhere from rear bottom side of engine or from automatic transmission. Metallic, grinding sound occurs at initial acceleration on uphills for few seconds then finishes. Sound looks like smth rotating metal bracket contacts with some other surface. I checked but did not find any suggestions? Can it be starter or exhaust leaks?

Thank you very much in advance.
