Jim,
My TD shook when I backed up for many years, especially when going up
hill.
The problem was the transmission mount where it is held down to the
frame with a forked bolt that attaches to a hole in the transmission
case casting. The hole on my tranny case had broken off, therefore there
was actually nothing attaching the tranny to the car and under load in
reverse it would jump around. This is a very weak point in these cars
and I'm sure many of them are broken. When I rebuilt the transmission a
few years ago I had a piece made to replace the hole on the transmission
from steel and bolted to the tranny case. The judder problem went away.
Perhaps yours is loose and when the rubber heats up on the transmission
mounts more movement is allowed. Be careful though, if you tighten it,
because too much tightening will break the piece off of the transmission
case.
