At a crossroads
I don't know what it's worth as-is, but it's probably worth 14k or 15k here in proper running shape. So is it worth it to fix it and keep it as a tow rig, or should I sell it as is and look for something else? I would probably go with a V10 Ex or pickup if I went that route.
Other than these two problems, the truck is solid. It tows great. It has 185k miles on it now. Important mods are in my signature.
My goal is to get back on the road by the end of this year.
What to do...
I vote replace the trans, install it yourself and do the up-pipes while you're in there.
The transmission really isn't that hard, it's just tedious and cumbersome, especially if you can't get the transfer case off first. I did mine with the t-case installed, took a trans jack as well as a floor back and some ratchet straps. Bellhousing bolts were simple, converter to flex plate boots were simple, turning the motor over sucked a bit but otherwise straight forward. You'll need about five feet of extensions to get to be top passenger side bellhousing bolt, otherwise the rest are easy enough to get to.
Could just throw an HD4R100 in there, dealer prices aren't all that bad - in the $2800-3400 range. Yeah, another $1600 gets you a built trans so that's another alternative... I still vote self install.
Up-piles will be about 3.2 million times easier with the trans out of the way. Which ever route you choose, get them done at the same time.
If so, then Matt's perspective is accurate.

Additionally, you already have $2000 in upgrades (according to your signature) if you go to a V10 Ex you will want/wish you had those.
Your Ex is probably paid for, generally when a trade is made upgrades are acquired and debt is incurred.
Best to you and I'm sure you will make the right decision for you and your needs.
I got my HD4R100 from a local dealer for $500 over dealer cost ($2350 dealer cost to ALL dealers). Another local dealer wanted $3800 and would not budge, even after I told them what the other quoted me. Said they couldn't make money on a deal like that, so they stuck to their price. Sooo, that came to $2850 plus tax. Some dealers will work with you, some won't. Find one that will. I installed mine in my driveway. By myself. Not the safest way to work, but I got it done. Didn't spend a dime on labor or someone's shop fees. First time doing a tranny in anything (EXCEPT AIRCRAFT), but I have a brain, eyes and hands that work. I did my research, asked questions here and I got it done. You can, too.
The HD4R100 does NOT come with a billet converter, and it is not triple disc. I replaced it with a billet converter of my choosing before I installed (one rated for a diesel application), along with a JW valve body. Easy to do both while it is sitting on the ground.
I did the TransGo HD2 kit in mine instead of a single valvebody swap, it also included a conversion from PWM lockup to on/off (way faster). A lot of people have been happy with a JW or BTS valvebody, I opted to go with the TransGo as it covers all three and not just the one.
If these are the only two significant issues with your 7.3 EX then it is well worth replacing the trans (I would most likely go with the HD4R100 after finding a dealer that will price it right) and the TC of your choice. And yeah, those up-pipes should be super easier with the trans out of the way.
If I recall, you spend a lot of time on the road towing and many long hauls, so why get away from the PSD which does so well with those chores to get into an unknown rig (that will needs some mods to make it as good-ish as your 7.3). Your EX with the new pipes and trans should serve for many more years dragging that TT around this great country.
Is that $2350 dealer cost accurate as of today? How sure are you about that number? I will definitely call around and see if I can get a better price after I get the money saved up.

One more thing - my 6.0 cooler is less than two years old. Given that the trans hasn't actually failed and filled the cooler with debris (fluid is fresh and red), and that I plan to install a screw-on filter for the new trans, do I need to replace it? I understand that Ford won't honor the warranty if I don't though. Will BTS honor the warranty without a new cooler? If I do the swap myself, how would Ford even know? Couldn't I just provide them with a photo-shopped receipt saying that I bought a new cooler?
Or should I just replace the thing?

You don't have to get new tunes. Gearhead was only interested in the valve body I had installed, not the TC from what I remember. That said, if it shifts too hard or too soft after install, you can adjust your tunes for free with them I believe. They just email a new one to you. Super simple.
For the 6.0 cooler, you don't have to replace it. Ford will not honor your warranty if you don't. The literature I got with the transmission stated the oil cooler had to be replaced and the lines and radiator flushed. I kept receipts in case something happened. Since I was already dumping their stamped steel TC in the thing, and replacing the valve body with a better one, I was not going to be able to get my warranty anyway. It is a choice I was comfortable with and made without much deliberation. If it breaks because of those two mods, then I will just learn how to fix it.

The question is why isn't there a part number that specifically mentions a 2000 Excursion? The dealers I've called so far haven't had any idea what an HD4R100 is or how to look it up. I gave them the part number and they can order it, but they say it doesn't match the VIN for my truck. I also see that the part numbers for 2000 SD's are different than the ones for 2001 SD's.
Here is the thread for mine when it went out and what I did:
https://www.ford-trucks.com/forums/1...fter-255k.html
After reading it, my memory was off a bit. It was $2150 dealer cost and I got it for $2650 + tax.
I have had terrible luck throughout my lifetime buying things and having them go bad shortly after purchase or just be DOA. If there's a bad one out there, I'll end up with it. I am a little nervous doing it with a $3000 transmission. I bought a PC last year and spent a week chasing down what ended up being defective memory. Several times I've had people tell me that they've literally never seen a DOA or defective so-and-so that I just bought. I bought a first-generation iPod back when they first came out and the disk died in it a couple days after I bought it. "First time ever" was what the Apple guy told me.
It just makes me nervous. Maybe I should just go with a BTS and not worry about it.
