Rick,
Based on your comments about how the gearbox was "bound up", I would
replace the first and third motion shaft bearings and all of the
needle bearings. Starting from the front of the box, there is a set of
needle bearings
where the third motion shaft goes into the end of the gear on the end
of the first motion shaft, a set for third gear, and a set for second
gear. The layshaft will either ride on two sets of needle bearings
or bushings. You should replace these as well.
While you have the box apart, replace all three synchro rings.
HTH,

Subject: transmission noise
I'm getting a lot of gear nashing noise when I accelerate and decelerate. I
seems to quiet out when the car reaches a comfortable rate of speed for the
chosen gear. It doesn't seem to matter if I'm in overdrive or not.
I just got this vehicle together after thirty years of sitting in a barn. I
didn't do to much to the tranny other than cleaning it out and replacing a
few
broken parts. During the cleanup, inspecting the gears themselves I observed
no broken teeth and moderate wear. The tranny was pretty bound up and
required
a lot of cleaning and lubricating to get it to turn freely.
I plan to rebuild the tranny over the winter, but does anybody have any
ideas
on what I should replace or look for that might account for this type of
noise
that happens only when the tranny is being pushed hard.
Sincerely
Rick Neves
