just a follow up. A rebuilt transmission shifts way better than one
with 182000 mostly city miles on it. no more 1-2 thud and the 3-2
downshift ka-chung is gone also. Basically it behaves like a normal
modern auto Transmission car now. No more driving around town in S
to avoid the nasty downshift around corners! Smooth operator.
now if I can only find the whole car vibration at 75 MPH, must be a
bent wheel as I have had four or five sets of new tires on it over
the years and now have replaced flex disks and the driveshaft
bearing hangar and rebuilt the tranny and it still vibrates. Or a
bent driveshaft I guess. Half shafts seem OK. Might be time to
spring for the 15" Bundt cake wheels.

Put the spare on the ground and move it around to see if anything
changes. I doubt your problem is a wheel. What you describe sounds
like an out of phase driveshaft. no known cure other than to send it
to the rebuilder in GA (but there is probably one in the LA area) or
to take it out and put it back together in the next spline (up to 33
times) until you get it in the right spline. Jim Cathey built a
lathe to find the sweet spot in his driveshaft, but most of us don't
have space and an adequate junk pile to salvage the needed parts from
to do that.
Another option is to buy a junkyard driveshaft and try it until you
get a good one. (I used this option) I lucked out the first time.
The moral of the story is to never let anyone buy yourself to touch
the driveshaft. In my case, some monkeys took it out without my
permission. They of course decided to slide the splines apart.
