Broken Flexplate
My truck is stuck in the driveway on account the teeth are worn on flex plate. Any recommendations for the procedure? Already have new bolts and part here. I have a pallet jack for the transmission/transfer case assembly or should I use another tool? Thanks for the help

A ratchet strap or two for securing the transmission to the jack. Once the transmission is separated from the engine and on its own what guarentees have you made for yourself that it's balanced on the pallet jack? More than once in my days of employment as a repair tech I was glad to have that transmission strapped to the jack before I tried lowering it.

I was going to thru bolt some lumber to the forks and make some type of cribbing with a strap. My friend is going to bring his atv jack over however I’m not confident it can hold the transmission and transfer case at once. Allegedly to do the fly wheel you only have to shift the transmission back.

What is the weight rating of the ATV jack and how large is the lifting plate? I cannot see how this would not work if it's designed to lift an ATV. Especially if it rolls on wheels somehow.

The other thing too is do you have a shop jack? You could make a plate that would attach to the lifting part.
I went and bought a Harbor Freight cheapo transmission jack that does the trick, but with the transmission/transfer cast assembly attached to it, it's giving everything it has to hold it up and the ratchet straps are required or it slides off.

Harbor Freight cheapo transmission jack works great on Zf5 with xfer case attached.
well worth the 100 spent
I used a forklift on my 88 toyota 4x4 clutch job with side shift
I have used regular jacks in the past and dropped a trans once squishing the pan
a trans jack is well worth the investment

You can drop it with just about any jack, but when it comes time to reinstall, one of these is very helpful due to the adjust-ability:

This is the one I bought and glad I kept it, I had to use it again because the pilot bearing half life on my truck is measured in minutes, not hours of operation or miles.

When I did my flexplate and torque converter I made a plate that bolted to a 2.5 ton floor jack and welded angle iron to catch the corners of the pan bolt flange. Then strapped the transmission to the plate. Also used another 2 ton floor jack back at the transfer case to help balance the weight. I managed it in the driveway solo in probably 2 1/2-3 hrs. I was actually a little surprised how easy it came out. Finding the right angle and combination of extensions to get on those upper bell housing bolts was probably the worst part.

I also second the remarks about welding up an adapter.
