Well Guys,
Here's what I see now that I've got it home.
Torque converter spinning as it should. I'm still not clear on observing the 'output flange spinning'.
I also note if I hand turn one rear tire, the other one spins in opposite direction. This occurs in Neutral and in Park...

with the TC spinning then the engine is turing everything in front of it and with the rear wheelturning the way you describe the shafts/ diff would appear to be good.
Conclusion...........tranny took a nose dive which other than changing oil/filter I dont know much more about repair. Need a tranny expert to chime in.

Thanks for your inputs.

So it sounds like you have verified that the shifter is actually moving the linkage, at the transmission, through each position. Yes? I don't mean you moving the linkage at the tranny, but rather having someone moving the selector inside the car while observing the linkage at the tranny. Or, sans an assistant; with engine running, in the air, moving the linkage at the tranny and observing if the wheels begin to move.
If moving the linkage at the tranny fails to engage the axles, that narrows the problem down to inside the box. I've never heard of a tranny failing this way. Usually there is a little more drama, and history of decay, accompanying the occasion.

Car was shifting a little hard. I adjusted to a degree via the modulator T pin. Was going to see if modulator held vacuum, check the vac line and the taughtness (or not) of the bowden cable.
No recent slippage. Running great.
Yes linkage to selector arm intact.

Forgive me for being pedantic, but I'm still not getting a clear picture of your troubleshooting. Have you verified that moving the shift selector inside the car is, or is not, moving the linkage at the trans.?

I just now put the car in gear while lifted and the tires moved only but an inch or two when put into Drive.

It is possible that while you were trying to adjust out the hard shift using the T that you adjusted too far and now, for whatever reason, it isn't shifting at all?
Have you tried unadjusting the T to see if this makes a difference?
(blind shot in the dark - but anything's worth a go before you pull the tranny).

I am very sorry that it wasn't something more simple. The immediate nature of the symptoms led me to have the hope for you that it was purely a linkage issue.

If the same can't be freely done in any other gear other than park and neutral, then this confirms a transmission failure. Simultaneously, it confirms that all other transaxle parts are functioning as they should. Output flange, differential, etc.

I wish it were simple too. I just find it odd no warnings - slippage, no shift..etc. Running like a charm until I started it up, and put it in drive.
