Performance auto transmission filter 87 on

[Mrmerlin]

I was doing a service on an 1987 Auto trans and found this filter. It has a sliding unit with seals at each end, front and back .
When the car is braked the slider moves forward to open the part of the filter that has the most fluid then when accelerating the slider moves to the rear to open the rear portion of the filter so to keep the trans from losing its fluid supply.
Roger has them about 45.00.
The part number on the filter is top line
126 277 08 95
next line is
67 002 54 156

This might be a good upgrade for the racer guys with auto transmissions
