Mercedes Repair Questions? Ask a Mechanic for Answers ASAP
Hi, if you have a whining noise from the transmission I would suggest having the transmission fluid and filter replaced. A clogged transmission filter can cause the transmission pump to make a whining noise. Since the transmission is working and has been making the noise for 30,000 miles I would not suspect that a transmission overhaul is needed.
Let me know if you have any questions.
