Do those signs mean the vehicle can’t be towed in the event of a breakdown ?

it can probably be flat towed for short distances but can’t be lifted and towed on 2 wheels (Same as Classic Land rover Defender) should be put on a flatbed. (Defender says to flat tow both gearboxes have to be in neutral.)

Interesting, logical both gearboxes to be in neutral. Last time I looked the Grenny only allowed High or Low locked/unlocked and no neutral position on transfer case selector

If thats the case it probebly cant be towed, well to get it unstuck would be fine but only short distances / offroad. It's a trailer job, fingers crossed its more reliable than land rovers are!!

Yes ~ I questioned this on a test drive and was told there was definitely no neutral; yet Greg Clark has stated the opposite?

Really wondering if the transmission is self lubricating or if it needs a pump. Would have been super nice to have full float with locking hubs. Will have to wait and see I guess.

Yeah, I was hoping that the axles would be full-float "one-ton" axles - given the curb weight of the Grenadier, and its payload capacity. But as soon as I saw they were 6-lug I figured they were semi-float. In the U.S. all our full-float one-ton axles are 8-lug. A full-float rear axle has many advantages...

Gearbox in neutral otherwise the parking brake won't release, not sure if there's a manual cable like they have on Land Rovers to emergency release. If you have totally lost all electrical power to the vehicle then there is a bolt you can screw in on the bottom of the gearbox to release the parking brake so it can be towed.

There's a pretty digestible write up about it here.

One thing I'm not sure on is if INEOS are changing out the standard plastic oil pan / oelwanne of the ZF box to an alloy or steel version. The plastic pan has an integrated filter assembly for the transmission fluid. As far as I'm aware the steel versions have a separate filter assembly. I forgot to look with my excitement when I saw the Grenadier in LA.

For reference Land Rover use the ZF plastic pan with additional underbody shielding to protect it.

As far as LR are concerned the transmission fluid is for life, but ZF say 70 or 75K if I remember correctly for a drain and refill.

Here are some photos of the new pan ready to go on my Disco4/LR4

Pretty sure the park brake is a manual cable type with an old fashioned lever, and not an electric one as implied here.

There’s a transmission brake in the gearbox and the parking brake (for the North Americans) or hand brake (for everyone else I believe) is a cable to the rear calipers. At least it appears to be. Not sure if it’s to a set of pads or shoes. But I’m someone has already worked that one out.

Happy new year everyone:)

This is a picture I took under the back seat showing the single wire handbrake cable coming from the lever in the front and operation two wires, one going to each wheel in the back

Your link includes a very good short video on the bolt. My only worry would be it doesn't seem to have any locknut/anti vibration arrangement. I think it might be worth checking the size & thread pitch and carrying a spare.

The usual way to secure such a nut is to give it a rounded shape with which it rests on the bolt. This will secure the nut.

I would be very surprised if this was different here.

I’ve been wondering about the rear as well - whether it’s a full float or semi.

FWIW, Defenders are 5 lug and full float-

Sadly - its semi-float. I forget where I read that though...

Let’s say that your Grenadier just dies-won’t start or comes to a halt- who do you call?
