I drive 25-30 miles 2x month. Car has 39,500 miles on it. Do I have to have transmission removed and change filter (or just exchange fluid) at 40,000 service?
Yes (stupid 10 character requirement…)
Pretty much the same answers that your other post got. Read the service schedule in your manual and see what a trusted mechanic would do for you . I would also suspect that there is other service that is needed on this very expensive vehicle.
In your previous thread you said you were a doctor . As my primary doctor says that some times sending a patient to a specialist is a good idea. Therefore I recommend you send your patient ( this Mercedes ) to a specialist .
No, the transmission does not have to be removed. The transmission filter can be replaced by removing the transmission pan on most models. A transmission service takes 1 to 1.5 hours.
