Guys,
I have a '91 YJ BUT 4.0 with Automatic Trans.
Where is the water coming from is my problem too. I'm kinda a newbe and just want to get it running (and go to Pismo Beach yet this summer
After an initial air release much like a tea pot, water has been gushing out of the back of the engine, probably out of the bell housing. Nothing else is wet. Not the heater-I connectetd heater hoses. Radiator is newish (~3 yrs) since one of my sons dinged up the front...
Q? What is different for 4.0 Automatic?
- Does the torque converter NEED to come off to replace the freeze plug(s)?
- If the drive shaft is removed, can everything slide back a few inches - then right back in???
- ie. Does the T-case really NEED to be seperated for only the freeze plug(s)

If you're leaking water from the back of your engine, you have 3 freeze plugs back there in the 4.0. One is on the back of the head, the other 2 are behind the flywheel. You will need to pull the trans to replace them. Whether or not you decide to separate the transfer case from the back of the trans or not, it is just one helluva lot easier to deal with the trans alone. It is hard to pull the trans back far enough to get a swing on your hammer/driver to reinstall the new plugs though, so you are likely going to have to get your trans on the ground. To replace the one in the rear of the cylinder head, you can drop the back of your engine down/jack up the front of the engine so that you can access this plug and drive in a new one. There isn't enough room to pull back the trans to get a swing as the bell will hit the tunnel before you get enough clearance. Likely one of these 3 freeze plugs is to blame, just replace all 3 of them. There is another small "freeze plug" back there, but I don't think it goes into the water jacket. Someone will know and fill us all in. Or I'll find out more and edit this post.

Edit--yeah, the small plug on the back of the 4.0 is over the oil gallery/end of the camshaft. But you'll be able to see which one is leaking when you get back there, replace all of them you can get to, if one is going, the others are likely to as well soon enough. They do make Brass freeze plugs.

Thanks for the input! Sooo... I will plan to Drop tranny instead of Lifting engine, and take off the T-case first.
This will be the project for next weekend! Then still 2 wkends left for Oceans Dunes at Pismo Beach!!

Update!
Last night I got home with some light left (and other projects complete
A neighbor ['54 CJ project] happened by and helped with flashlight and mirror.
The HEAD freeze plug is the one leaking. Not inside the bell housing!!!
Looking for the path of least resistance-Not pulling the engine or dropping the tranny- after looking at how to get room by loosening the motor mounts and tipping everything he said 'why not cut a hole in the firewall????' -SO-
Q? Can you think of a good reason why NOT to cut a hole under the AC to get at the freeze plug?? And then make a cover for it…

Nothing wrong with cutting a hole thru the firewall for access to something, then covering it with a plate. However, you may find that this is more difficult than you think. The back of the head is higher up the firewall than you think, and again, it will be tough to get enough room to swing a hammer to drive in the new plug, or to remove the other one. It could be possible that you could pull the skid plate and lower the trans/t-case which will tip the back of the engine significantly downward (and also the front of the engine upward, so make sure nothing gets munched up-wires, radiator, hoses) and this may allow you to cut the hole lower on the firewall and perhaps encompass some of the top of the tunnel. Before you start to cut, do the lowering part and see if you can get a swing in there; having the under dash AC unit makes this approach significantly more difficult of course.
For me, I'd pull the trans and if I couldn't reach still with tipping, the motor would come out. It really isn't that big of a job, it just has some painful components. Generally freeze plugs start leaking because they have rusted thru from the inside out, and if one went, what is the condition of the rest of them? You didn't just get one unit from the island of misfit freezeplugs, they're all likely to wear out over a similar timespan and they're all the same age suffering from the same conditions. Get brass freeze plugs as a set, replace them all unless you perhaps relish doing the job again for another painful to reach freeze plug. Just my thoughts.

Quick update: All better, but I cheated
As mostly a newby, I spent all Friday under there cleaning out oily sand. Did some easy stuff like pull the starter (that I put on w/in the last 6 mths) torque cover and drive shafts.
Then I started looking at rusted parts and couldn’t really find all the bolts. So Saturday I threw on the skid plate and pulled it to a shop. Got it back yesterday. Was afraid I wouldn’t be able to get it back together. Except for being $550 lighter, all’s well.
Thanks for the help and encouragement though. I will need more shortly as I’m hoping to put in a SOA lift this winter and get on 35’s! Rubicon next yr?!

New Revised Update: 
A week ago I picked up YJ from shop. Started great, as it had since new starter & battery within 6 mths.
Drove & shifted fine, but a little cross threaded. Ie D was almost N; N was almost R; and R was close to P.
Then next day it drifted into Reverse from park (almost taking off the passenger door). A day or two later it wouldn’t start at all. No sound at all. Jumped it – still no sound at all, not just the battery.
I assumed it was a linkage adjust problem not actually being in Park which is why it was not turning over.
I towed it back to said mechanic. He replaced the Neutral kill switch but now is blaming the non-start on metal shavings in the transmission pan…
Now it is 23 yrs old, but that is not the reason not to start. I feel they screwed something up. Know it and are running from it.
Towing it home tonight. What questions should I ask him when I pick it up? I probably could/should rebuild the tranas, but that’s not the reason it won’t strart. Any thoughts are welcomed.

Towed it home. This cable is obviously loose. It's not really coming from the column shifter. Are there any pics around of what it is suposed to look like???
