Transmission service on these older Mercedes is very often neglected and it is something you can do yourself. It should be done every 30,000 miles or every 5 years (whichever comes first). After you watch this video you will find out why you should do it yourself!
In this 5 and a half minute video Kent will show you how to replace the o-ring seal at the base of the dip stick / fill tube going into the automatic transmission case on the right side.
This is becoming one of the common transmission fluid leaks on these older automatics. If the trans is leaking fluid in small puddles while the car sits for longer periods suspect this seal. You can be fooled thinking it is coming from the pan gasket.

The bowden cable runs from the transmission to the throttle linkage on many Mercedes from the early 1980's up through the early mid 1990's. When this cable fails or is out of adjustment the transmission will either shift too early or too late.

I have received so many emails on this topic that I had to sit down and write a very detailed manual over 130 pages in length! Let's face it! Diesel automatic transmissions can be troublesome, particularly those models that use vacuum to control shifts.
This manual is part of our Advanced DIY Mechanic Series. It covers advanced procedures in simple terms with photos to illustrate every step. The format size is 8.5 x 7 inches. It is printed on 28 pound stock paper and is wire bound to allow it to stay open when on your workbench.
INCLUDES TRANSMISSION PEAK TUNING MANUAL. DO NOT ORDER SEPARATELY
This unique kit will allow you to hook up a 30 in HG vacuum gauge between your vacuum control shifting valve (VCV) and your transmission modulator to test the VCV for proper function and to tune it for peak shifting performance.
Applicable to 114 115 116 123 and 126 Chassis, years and models listed above. Troubleshooting an annoying shift problem must first start with the vacuum modulator.
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.
This is a good used original genuine transmission vacuum modulator valve with adjustment key and cap. Failure of this part can lead to harsh or jerking shifts and in some cases prevent the transmission from shifting into 4th gear.
If your clutch is making growling noise when you push the pedal in these are the parts you need to fix it. You might want to consider replacing the pressure plate and disc while you have the transmission out.
