In my case I found that by overextending the solenoid plunger a millimeter or
two (that small a difference) it would never work. The theory was that car
vibration or bumps would bring the plunger back into magnetic range so
sometimes
it worked.
I had the cover off the transmission and the only time I could duplicate a
solenoid not working was by just slightly extending the solenoid plunger so
that
it came out of magnetic range. And I had tried several solenoids borrowed
from other cars where we knew they worked.
The BJ8 shop manual I have on hand does not show a rubber bumper but it is
the same setup as a BN4, only the later style has a cover over the plunger and
arm assembly. I have seen BJ8 transmissions with a screw run up through the
bottom to act as a stop. Not really sure what was there originally.
When I finally diagnosed my problem some 8 years ago many of the listers
tried the same fix and reported success.

Hey Jim,
Could this same problem occur with the BJ8 Transmission/overdrive. I've
had exactly that intermittent failure that has eluded diagnosis for years.
