Please send me your old ZF transmission pan and filter

Gotcha, for flat towing you most certainly need to actuate the T-case emergency actuator. But in an emergency, which is pretty much always going to be slow speed, you can just set the T-case in neutral via the shifter in the cab. It's not perfect, but it won't cause any damage. You can move the truck fast enough to get it out of the mud or water and then properly set it to neutral from underneath at that point.

This would preserve warranty and is pretty much fool proof. I would suggest you practice it a few times though to get a feel for it. Most people have trouble splitting hairs, but once you do it a time or two you won't have issue anymore.

That's the gist.
One small correction: The goal is to set the transmission into neutral via this lever but only if you cannot access the neutral screw on the transfer case - which remains the preferred and approved method. Two separate methods. If you cannot access the transfer case neutral screw due to environmental then getting your hand onto the parking pawl lever is probably a no-go as well, hence the remote kit.

We're a fair way down the "it's-5pm-and-today-has-really-gone-to-$hit" list if you actually need to do this but it might be enough to drag your vehicle out of a river before you need to phone a friend who knows something about rivers and drowned engines. No names, please.

Hey @scottg. Sorry this has taken your ZF pan thread off track. It's kinda relevant-ish.

But who cares about disengaging the parking pawl if you can set the T-case in neutral from the cab quickly and easily. Especially if you have to modify the truck to instal a manual parking pawl kit. The truck already achieves what you are looking for without modification.

Are you talking about setting the transfer case shift lever at a mid point and hoping it stays there?

The hope spring? They do say it stays put!

Yes, it stays just fine. It will not go back into gear without external input. Again this is just to keep you from swimming or becoming one with the mud. Then you properly set neutral under the truck after recovery and before high speed flat towing.

Regardless, you do not want to flat tow a Grenadier by just putting the trans in neutral.
