Mercedes Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is***** you for the question. Typically this is a problem with the valve body in the transmission. The valve body may have some debris stuck in it or a sticking solenoid. It can also possibly be the onset of a transmission failure. Can you tell me if the check engine light is coming on.
Some of the time a fluid change will help. Since the check engine light is on the best thing to do is to have the computer scanned for codes. Most auto parts stores will do this for free. If you have this done and bring me the codes I can tell you what they mean and what may be going on.
