Sold in a set of four. These have to be the strongest magnets in the World! You do not put them inside the pan. Rather you spread them out on the outside bottom of the transmission pan as shown in the picture below. Talk about an easy install! You don't even need to jack the car up!

I don't think there is any owner out there who has owned a 1978 to 1993 diesel automatic for any length of time and who has not had some sort of shift problem with the transmission. Maybe it was just a little jerk or a slipping shift. Maybe the rear end clunked hard when you came to a stop.
If your transmission is shifting too soon it can really rob your car of power and acceleration. If it is shifting too late it can be very loud and annoying and even affect fuel economy.
If you are experiencing very hard or less than perfect shifts, a failed transmission modulator could be the problem. New Genuine Mercedes part. This unit is an upgrade over the original. It has a better thrust pin design which is less prone to cause pressure variations in cold weather.

Bad rear mount can cause excessive engine vibration. No instructions included at this time.
