Easily missed on page 18 of the Aug '19 JEC mag is a mention of Motor Legends developing a replacement gearbox suitable for the V12.
I have no other details, but thought it may be of interest to some.

Re: 6 speed auto box for the V12
Looking at their web site, I suspect it will be very pricey. They're also talking of making their own 9.2 ltr 1000bhp V12.
On days when I've nothing better to do, I daydream about fitting a second-hand 6-speed box from an X350 to my XJS. It would need new electronics to control it, but I'm sure that's something a £35 Raspberry Pi could handle

£11K for a new box or £9K for a used box. I'll stick with my 5-speed manual if its all the same
