The Brass Thrust Washers are a weak point in the OD and are often
broken....however, not sure if that would cause the noise.
My transmission had a broken brass ring but did not have the rattling noise.
What Gear does it rattle in?
I wonder if the brass fork is worn such that it does not fully engage?
Does it ever pop out of gear?

Mark,
By applying pressure what you are doing is moving the 3/4th slider forward.
So the wild guess is that you have some sort of end float/thrust issue.
Unfortunately it could be on the main shaft, the lay gear or the O/D. With
the sudden onset, I would guess it is one of the brass thrust washers in the
O/D has broken. You might be able to inspect for that by removing the
accumulator housing cover. Pretty tight. Maybe brass in the filter plug.

Listers,
A few months ago I completed a rebuild of the transmission and O/D in
my BJ8. Everything from the rear engine plate to the diff was
removed, dismantled, inspected, and worn parts replaced. The car has
120 K original miles on it. While it was apart I replaced every
bearing throughout the gearbox and O/D, synchro rings, and a worn
layshaft. All the gears appeared sound and whole. I also replaced the
clutch and U-joints and had the propeller shaft balanced. I now have
about 600 miles on the car since re-installing everything. Yesterday
on my birthday I went for a little celebratory drive. As I drove I
noticed that the gearbox now has a low rattley sounding growl. If I
allow my hand to rest on the gear shift lever the sound stops
immediately. As soon as I remove any pressure on the lever the sound
returns. I welcome any thoughts as to the cause of the sound.
