123 107 126 201 124 722.3x and 722.4x Transmission Modulator O-ring Seal

For re-sealing green and black modulators on most 1981 to 1993 models.

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.

1982 to 1995 Auto Transmission Dipstick Tube Seal

Fits all models with the 722.315 and most 722.4 transmissions - see list below

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.

Troubleshooting Older Diesel Automatic Transmission Shift Problems - On Demand Video

Knowing where each component is located and what it does is the start of solving externally caused shift problems

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.

These will work in any automatic transmission from 1968 up to 2004 including the 722.6 transmission. The 7G 722.9 has magnets in it.

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.

1981 to 1995 722.3 722.4 722.5 New Transmission Pan Replacement w/ Magnets

Fits many models during that period. See complete list below. Late W123, Late R107, W126, W201, W124, R129 and W140

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.
