Interesting question!
I had similar issues far far far away from civilization. It started with getting stuck in deep mud/on a ledge, leading to "electrical error please stop safely". I'm not really sure if the problems are identical because I think my cause was a charger/second battery / dc-dc errors (and many more) resulting in an empty battery resulting in even more errors. One of them was a continues beeping from the electrical trailer hitch deployment panel in the back. At first I didn't manage to salve the car and it was stuck in nomansland for a few days. No way for a flatbed to reach the place. But later when I wanted to pull the car out with help of another car I ran into this: https://www.defender2.net/forum/topic93574.html Basically the car without power is a fricking 3,5ton anchor. You cannot pull it due to the gear being in park. And releasing the back mounted parking brakes is a major PITA but managable (if you have the right tools which are NOT in a normal toolkit, haven't found the "star"-bit yet). Nobody at JLR could provide me with an answer about the 'park to neutral' lever being gone and what you can do in these situations. I've asked many many people. |

Well, here comes the old man brigade.. all this new fangled stuff is nothing but trouble. I know times move on, but you know a few months ago I was in some dark corner of Angola in a hotel when the power and internet failed. Really leaves you with very little else than reading a book.. for a few days. I know not relevant because we are so used to things just working, but when they don't you find simple things are actually better.
If I was to cross say Australia, I probably rather drive something simple and bomb proof.. e.i. not a modern Landrover product. They are designed for domestic settings with internet connections and digital support a phone call away. |

lf only the new Defender or Grenadier could be specified with a manual gearbox. And a proper mechanical handbrake that you pull up to engage.
Both are fitted to our 2020 Jimny, so it's still possible. |

The Grenadier does have a proper old-fashioned handbrake, not one of these stupid and unnecessary electric ones. I believe it has a reasonably simple mechanical park release on the gearbox as well.
It's no wonder that the traffic wombles hate electric parking brakes. Image 3.5 tonnes of immobile car in lane 2 of the M1 in rush hour. |

Well that's one big advantage that the Grenadier has then. You don't want an Overlander that can brick itself and be immovable in the middle of nowhere.
Surely The door is open for an aftermarket supplier to produce a kit for disabling the brakes on a Defender in these circumstances. Or some sort of remote add-on to enable the release lever to be operated from the cab. |

It appears that the Grenadier can also be put into neutral from park reasonably easily with a dead battery. although this does unfortunately mean working from underneath. There is a lever with a screw beneath it, screwing the screw in pushes the lever which puts the transmission in neutral. I cannot see why moving the lever directly with a screwdriver or pry bar wouldn't achieve the same result. I still wouldn't like to have to do this in a live lane on a busy motorway.
The Grenadier apparently uses a screw with a 13mm hex head and a specially shaped spanner is included in the tool kit for the purpose (the standard ZF uses a socket head cap screw). Sadly I don't have a Grenadier to try this procedure on, but I am both impressed and unsurprised that team Ineos thought about this and made it easy.

Defenders use the same gearbox so I’d imagine the procedure is similar.

that's interesting. When I'm back home (16000 km to go) I'll put mine on the bridge to find out. I'm not quite sure if 'the defenders' are all exactly equal because there is a difference between 2022 2023 models.
Like stated; mine 2023 P400e has NO park/neutral lever anymore where a 2022 P300 does have one. Regarding the ZF document above the bolt on the Defender both in practice and in the workplace manual does look different in form and location. That's not really promising. See here:  Click image to enlarge @lightning; The parking brake isn't the main issue here. With a torx 40 + big "star" socket you could undo the parking brake in 5 minutes.

 Plenty of modern Land Rover owners in Oz take them into the nether regions, it’s seen as a
challenge..  and if under warranty, LR assist have to come and get you.. if not then one
of the other motoring organisations.. That said LR products are still a minority in Oz generally compared to the Land Cruiser and Patrol Brigades .. yet another pommie bar steward down under MY20 110 P400 SE Defender MY10 3.0 RR Sport |

It looks to me as though the bolt and lever have been deleted from the LR version of the box, and the spigot to which the lever is attached on the standard ZF has the flat for the spanner. As long as the spigot is still present the method is probably the same. What's the betting that the spigot has been deleted for "value engineering" reasons? |
