A few little electric issues on my LR3.

Per the link below, install a new brake light switch and install all new genuine Land Rover tail light bulbs. Back in 2006, LR was installing new trannys because the owner had installed a non genuine tail light bulb. The false error messages, and that is what you are getting, are generated by the engine computer, not the tranny.
In addition to the bulbs, more common now is just that the Brake Light Switch has deteriorated - it appears to work OK but the second set of Normally Closed contacts to the ABS and computers has been fouled by the Brake Light Normally Open contacts.

If you had a Toyota with a brake light switch problem, it does not start so I think we are better off just looking at nasty scary messages. On the other hand, for Toyota owners, the goofy brake light switch is a recall so....

Okay, now what? I got a new hood switch from British Atlantic (great folks!) and a new battery. I'm still having the same issues. "Bonnet Open" message flashes up about every 20-30 seconds. Periodically each time I drive it I get the "Transmission Fault!" messaage. The transmission works fine, with one exception: The "D" on the shifter remains lit all of the time, even when in park. I get no response when I shift into Sport mode.

One thing that messes up the electronics is pouring coffee or other liquids on either the switches or shifter; the electronic stuff mounted on the centre consul.
For starters however, I would disconnect the connector to the hood switch and ground the two pins together. That for certain should show as a bonnet concern - yes it does now, but then disconnecting the jumper should eliminate the warning - which it does not apparently.
I would then try to follow the bonnet wiring cable as far as I could to see if it appears damaged - shorted together, that sort of thing.
With the D light always illuminated and the sport function not working, I would be suspicious of the shifter switches myself - due to fluid ingress.
