ok so I been hearing this whinning sound almost like a super charger. from engine bay when car is warm at 80 centigrade. I thought it was my trans so I got a filter/gasket/fluid change but I still hear it. my idler pulley arm is moving a bit. but I only hear it when accelerating. also im not sure if my car is a 5 speed or 4. but when driving I only count 3 shifts and when doing the speed limit which is 70mph on freeway it stays at 2500 rpm the entire time. is that normal for a 98 e320 w210? the other thing is when im accelerating im hearing this gurgle type tick then it goes away, but only when I accelerate for the 1st 2 shifts then I don't hear it let alone when in idle. anyone have this same problem? I don't want to have to replace the engine etc. I think I have the long engine. its big with a big fan so theres a clutch buts no engine lights or codes on and this just started a couple weeks now. own the car since September this year. if its not engine it has to be bearings or maybe trans mount/bushing. just did a 2nd trans today, but a partial drain was done 3 days ago didn't have all the tools. much help would be great.
