I haven't seen anyone respond that the transmission TSB was not great so I may as well chime in. I have an early car with minimal shudder. The main frustration was clunky 1-2 shifts and lack of progressivity in the shift strategy. It would lug at low to mid throttle then suddenly with a little more throttle it became rev happy Ricky Racer.
Now it is better at launch and what little shudder there was is gone. At very light throttle it is still fine but anything more and it's suddenly back to its Ricky Racer ways. I'm talking 4000 to 5000 rpm before it shifts and I'm just barely accelerating. Part of the issue seems to be temperature related. At 40F it's not so bad. If it is 0F outside it is terrible. I can hardly wait for a truly cold day!
UPDATE: SEE POST 702
