If your modulator is working ok, but leaking transmission fluid, you may only need to replace the inexpensive oring ( o ring ). You do have to be careful when removing the modulator from the transmission. For instructions (available separately) see related products below.
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.
Illustrated 6 page step-by-step instructions for proper removal and installation of the modulator upgrade for the years and models noted here. Includes how-to specific details for using the new adjustment cap on the upgraded OEM modulators now available. These are installation instructions only.
The plastic shift bushing is a very common part that needs to be replaced on older Mercedes. Can you believe it is the exact same part that was used on all models for over 25 years! It is an inexpensive part that can cause big problems if it breaks out.
If you have ever tried to remove and reinstall a shift rod attachment clip under your Benz you know how frustrating it can be.
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.
In this 24-minute instructional video, Kent shows you more than just how to change the transmission filter and the pan.
In this detailed 22-minute video instruction, Kent will show you how to use his kit to perform a power drain on most 1965 to 1995 automatic transmission.
Yes, YOU can fully drain all your transmission without using any type of "power flush." Full detailed video instructions are included. This kit is easy to connect and the process is quick and clean. Watch Kent's YouTube video below for full details.
Kent is a firm believer in using these strong magnets inside a transmission pan to help extend its useful life.
They should be placed toward the rear of the pan as shown in the picture below.
These transmission pans get "out of shape" due to over-torquing the bolts. That crushes the stops (see below), and when that happens, it is very hard to get the pan seal not to leak. Your best option if you are doing a transmission service is to replace the pan.
This guide will explain how to properly change the fluid and filter in your late 123, 126, 201, 124, late 107 chassis Mercedes as well as early 129 and 140 chassis. This includes model years from 1982 to 1993.
