Well, after WindoWelding the firewall side tranny roll resistor, the sound didn't go away. New hypothesis is that the fender transmission mount (under the intake) is shot, probably with the inner bolt broken. This accounts for the sound with the transmission side moving, and it is also a reported problem on the board.
Since it appears that a search didn't return the full solution to this problem, is there a rubber insert available in the aftermarket, or is the shot one reused with a new, higher grade through-bolt?
