I would imagine all the bits are available for the mechanical side of the change. The diesel came with a manual box so all bits to take the R380 in the P38 are available.
Not sure how much of an electrical/electronic nightmare it maybe.
But I would have to say very doable with patience and time for sure.
Uness you are getting somebody else to do it then it could get costly.
Why?

+1 on Why ?
A few guesses:
- BECM (& possibly engine ECU) will require settings changed.
- Modified wiring for Reverse & Neutral switches.
- Bell housing & Clutch bits, plus clutch master ?
- Replacement pedal assembly ?
Again why ?

I just prefer manuals and wanted to know wether it's something an amateur could do themselves.
If you need something to do I am sure it is possible for a reasonably mechanical savvy person.
As said the electrics/electronics would probably be more of a challenge. But wiring diagrams are available so I dont see why not.
It was (the 4.0) fitted in the Disco as a manual so the settings to change should be available in the ECU and the BECM has a manual setting, if they work together is another thing. So that said do you have a Nanocom?

I seem to remember that, despite the allegedly high standards of police vehicle maintenance, these cars were usually on their third engine by the time they were cast out of service.

BECM & GEMS definitely have gearbox type setting. Can't find anything in Thor or EDC.

It’s not like a straight swap or for the feint of heart.
You don’t have a clutch pedal or associated requirements like master/slave cylinders, cooling for it, electrics all sorts of niggles before you even get to adapting a box to fit. That doesn’t mean it can’t be done just rather involved, and it won’t be drivable the whole time it takes.
One member even put a manual box in an L322 which he uses regularly so anything is possible if you aremad committed enough.
Have a good read through related historic posts in the searchbar while you ponder your possibilities. It’s been discussed previously and if you are serious about it there’s a lot of homework to do
