Adjusting Automatic Transmission Mechanical Shift Points for Peak Performance - On Demand Video

If your transmission is shifting too soon or too late - a quick no cost D.I.Y. adjustment

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.  Adjusting the shift points is a very easy procedure on most older Mercedes that use a Bowden cable to change the internal control pressure inside the transmission.
