I probably had an FTP the day before heading on holiday but I wasn't having any of it so I just worked around the problem all day.
I lost the ability to shift into park but all the other positions work.
The relay that normally clicks when you move the shifter does click, but not when moved between R and P.
The only diagnosis I did was to pull the column apart and make sure the contacts were touching and to jump the contact to make sure it was beyond the column.
1. The clicking shift relay is one single relay?
2. The shift relay is in the dash under the dash top cover?
If I have to pull the dash cover I'll document it with photos.

Ross, it may be a fault at the auctator on gearbox. If nothing else works take plug from actuator and test same, use 12 volt test lamp to ensure same receiving power.You can also test actuator by placing 12 volt over each pin on actuator, (same should move gear selector).Disconnect actuator lever from gearbox before you start to reduce possibility of damaging same

The earlier Shadows used a multipin connector at the gearbox actuator. I would check for corrosion and add some dielectric grease on the pins.

Good luck Ross. I am sure you will crack this one.... it seems like it will be an easy repair for you.

Finally got around to addressing thd park situation on srh 8824.
I popped the clamshell on the column and 12v to the swiper and 12v to the wire on the other side going to the harness.
I popped the connector on the shift servo and plotted the pinouts. No 12v on any pin when in park.I think that the A pin is actually park so don't trust the mapping.
Checked the firewall connector behind the brake reservoir and mapped the pinouts.
After cleaning the firewall connector I got power to the connector at the shift servo when putting the car into park, but still the servo won'y shift.
I will have a look at the wiring diagram, but I think I have to pull and repair the servo.
That's the current state of the park shift mystery.

I recall from the dim past that the R-R/B T400 actuator is the same as the one used with the early 1960's Chrysler "push button" Torqueflite automatic transmissions fitted to the R and S series Valiant and other models.
This might help if the actuator is the problem.

Hi David, I wonder why RR/B didn't use buttons instead, seems much better idea to me.
I like the idea of a knob like jag BMW etc, think I'll mod mine.

De-oxit and dielectric grease is your friend with these connectors.

I used a SS brush and Triflow? Spray lube. I don't know much about it but I have a case of it.
Good to know. I will just fix this one. Things don't break as much as get dirty or out of adjustment. I'm hoping a clean and adjustment does it up.

The long lead time for the Shadow project was most likely the reason why push buttons were not considered.
Also, it is interesting push button transmission selection had a short life and had disappeared by the mid-1960's being replaced by the ubiquitous floor-mounted selector and bucket seats. The traditional front bench seat disappeared as well and the mandating of front seat belts which meant the end of your girlfriend sitting close to you.
Those were the days.......................
