Flat towing of grenadier

[Lt403]

Why can’t this vehicle be flat towed? I am surprised that this is not available .
It would be another option to be towed behind an RV

The transfer case does not have a neutral position. Unlike the classic Defender and mo
st part time 4WD's.

I though you crawl under it and screw the set screw in...than puts the transfer case in neutral.

It does.

The user manual warns you not to flat tow it any real distance.

That it does.
It isn't that big of a job to disconnect both driveshafts from axles and suspend them for towing.

I'm learning to being more aware about how old my knowledge is, but most autos don't have a rear oil pump just one in the front driven by the engine via the torque converter. The engine needs to be running to make oil pressure for transmission cooling, cleaning, lubrication and control. Towing an auto any significant distance or at speed with the transmission output shaft being driven by the drivetrain will do damage to the transmission due to a lack of oil pressure.
Caveat: I cannot confirm if the ZF8HPx series has a rear oil pump.

The Grenadier has the neutral stop bolt in the transfer case to isolate the auto transmission from the drivetrain (and circumvent the auto trans parking pawl if the vehicle is inoperable), but I'm of the opinion this method is only so the vehicle can be recovered onto a flatbed trailer hence the warning in the owner's manual.

Not via the Transfer Lever, unlike the examples i provided

No, but there's a neutral. My guess is INEOS is not certain the t-case will stay in neutral forever, and for fear of a catastrophic breakdown they say don't tow it for any extended duration.

 

[Mike Morrison]

Why Ineos elected not to have a neutral and have to climb under the vehicle malarkey is anyone’s guess.
There is so much they got right, but things like this makes one wonder if the engineers were overridden by the suits and beancounters.

Where neutral is selected within the transfer case gear train and how this effects the lubrication would be the reason the the car can't be flat towed long distances.
