Default Removing Transmission and Transfer Case. Will Engine need Supporting?

Hello Everyone.
I'm parting out my 1996.
If I remove the Transmission and t case first will the engine stay in place ok?

I am trying to remove as much as possible while it is still on the tires for safety reasons.
Once the axles and lift are removed I don't really want to be crawling around under there.

I should also add:
4L I6, AW4 Auto, NP242

On mine, there were zero issues when the engine was only supported by the right and the left engine mounts, with the transfer case / transmission / rear mount removed.

Use a transmission jack w/ safety chains when removing / replacing the transmission and the transfer case. Both are heavy and awkward when working under the vehicle.

Safety first.

Never, ever, ever work on a vehicle supported only by jacks.

Raise the vehicle then lower the appropriate frame locations onto solid jack stands. Work on a solid level surface. Block both sides of the far tires when lifting.

Thanks wingless. That's good news, and thanks for the safety tips.
Definitely blocking all 4 wheels and leaving them on the ground while under there with no driveshafts.

On my vehicle the chassis needed to be raised and set onto jack stands as-high as-possible and the detached transmission needed to be moved from the transmission jack to plywood setting on the ground, so that I could slide the transmission out from under the vehicle.

The front of the transmission has a large bell housing that must clear the side frame rails. Sliding on the ground was the only way I could remove this from under the vehicle.

i would support the engine, unless you don't care about the stock rubber engine mounts. they tear quite easily, especially if you have an oil leak and saturated the engine mounts.

I'll take a measurement for clearance before I get in a jamb.
The rubber mounts I will either re-use if I can protect them or replace.

If you want to save the engine mounts, place a scissor jack under the oil pan w/ a 1' piece of 2x4 to spread the load.
