Transmission leak
I've seen this talked about before and it's happened to me before aswell but now the tranny is leaking onto my Ypipe a couple times per week and it's giving me a hard time when I try to reverse. revs drop and it stalls if I don't give it enough gas.
So I know I have to change the seal but Ford is telling me the torque converter will need to be replaced but another transmission shop told me once the seal is changed and fluid level set appropriately I shouldn't have the reversing problem anymore?
Is this something I could attempt myself... looks almost like I'd have to move the exhaust to drop the tranny...

If the torque converter hub doesn't have any damage you can reuse the converter. If the surface has damage you need a new converter. I don't know if you can do it yourself or not. Be aware that the trans weighs 270 pounds. The transfer case adds more weight.

It's not simple to check the fluid level though... you drive for a bit, park and check level... add a bit and then you can't check it anymore because it's cold and the fluid is like molasses and won't drip all the way down for days. When you check all you see is a dipstick with 2 feet of red goo hanging off of it...
I've been trying to buy a 2nd X to run while I work on this one... but all I can find in my budget range are ones with 500k+ kilometers... and to be honest... I think that's quite alright
But this transmission leaking/reverse stalling thing has been the most tedious thing I've had to deal with up to now... I don't want to pay $500 to change a $30 seal...

Mark, if I try and tackle this myself (I'm currently not working until June so I have plenty of time) what parts will I need? I see the viton seal is the one I should get... but I've read something about changing bushings or some copper piece while I'm in there?

You need the Viton seal, a torque converter hub bushing, and a pump seal and gasket. All together these parts should be no more than $30.
If the torque converter hub is damaged you'll need a new torque converter, too.

If I go to my local Ford dealership will they sell me a viton seal? Do I need to ask for it specifically or is it only an aftermarket seal?

If your tranny is low enough to cause trouble when going into reverse you need to get the level back up the the full hot mark ASAP or you could cause major damage to your tranny. Also usually when transmissions are low they will slip or take a long time to go into gear not stall the engine. That sounds like a separate issue IMHO.

Low transmission fluid WILL cause an engine stall. When the fluid is low line pressure drops. The main regulator valve has a priority function that will cut off the pressure feed to the torque converter when line is too low. Without pressure to hold off the converter clutch it can drift on and that will stall the engine. That's a fact, not MHO.
