That vacuum module (its green in color) is like 30 bucks for a new one. But if failed will not cause the car to not go in gear, many break the vacuum line during an intake refresh without realizing it then they wonder why their car is shifting hard. Or the module could fail which seem to be the case with yours.

Craig.......sorry to hear the tranny has such issues.
If I were you Id seek further counsel as to cost of repair given the possibility of fragments throughout the assembly versus a complete new or refurbed gbox.
The rest of the car and budget of course will play large......good luck.

Hoping its something simple, like low fluid or some problem with the shift linkage cable or linkage mechanism. Maybe, like lots of 928 issues, multiple problems.
(I've had an otherwise operational transmission with a broken parking pawl, and it doesn't sound like the issue on your car --- unless somebody tried to drag it away while it was parked and broke everything inside including the pawl and the operating parts.)
Here are some pictures of the shift linkage and axle.
Maybe its somehow spinning inside.
(Looking for parking pawl pictures, its on the output shaft end of trans.)

Thanks for the thought.
If I find damaged component(s) when I drop the pan (spring, clips,other sundry items...) is it a mortal sign for the transmission or can (I would think) these items be replaced and re-seated ?

the hot setup would be to buy a brand new transmission from GB it would be a plug and play install

Hey Jim.
I let it alone for a few days until the trans pan gasket, filter, and replacement modulator came in. I didn't want to drop the pan and leave it open for days. According to tracking, should be here this afternoon. I will post back.
Thanks,
Craig

Once I put the vacuum unit back, I will next drop the pan and see what's there.
Thanks,

Not sure the failure modes of the modulator but hopefully the failure was contained and not spread throughout........good news I believe.
What does the old modulator look like?
