Hello group, Just registered and new to this site.

I have a 98 c280 and just the other day while driving and coming to a traffic light I began hearing a loud noise coming from under the hood. I pulled over and open the hood the noise is coming from the engine belt area (if that’s what you call it) it squeaks and makes a loud noise. The vehicles performance has been for months sluggish. Just yesterday I am unable to put the vehicle into 4-3-2 over drive. The auto shift lets me to put it from park to drive and can’t go any further.


Anyone know whats wrong
