Nice pictures of the Trans Scott. Like I said about your axle work, I wouldn't hesitate to use it in peeJ (mine).

I just had the pleasure of meeting Scott in person! We had the opportunity to discuss this issue. In the end when Scott tore the trans down, he discovered the issue. Considerable wear was allowing...
Up until the mid to late 60's T90's had 16 teeth. For some reason the tooth count was phased in to 15 in the late 60's. You will find both 16 and 15 in T90's from the mid 60's and later. The gears...
You aren't annoying anyone Scott. This is what the forum is for, and this is how we get the information! There is a lot of support captured here over many years. Be sure to search the tech sections...
Pull it out Scott. Lets take a look at the reverse idler.
At this point I would say it can only be one thing. The reverse idler is the only item that is isolated in turning the output in reverse gear. It sounds like the bearings/shaft/gear assembly has some...
Scott, are you saying you have no driveshafts hooked up and you are turning the output yoke and it wont turn smoothly clockwise? I am assuming you put it in a gear and depress the clutch and turn the...
Scott it is possible you have a brake shoe or component broken/loose in a rear drum or the emergency brake that is jamming up when the drum spins backwards. Crazier things have happened. I cant think...
I wouldn't run it with the suspension hanging down at a high RPM or, for long. The u-joints are opperating at the highest angle possable when the suspension is hanging. All that said your problem is...
Put it back together Scott, I cant see a thing wrong that would keep it from moving in reverse. There must be a body under the car. I am going to say something strange is happening like the engine is...
Scott, with what you are describing and what we see in the pictures, I cant spot anything mechanically preventing reverse. The only thing left is the cover. The transmission looks OK to transfer...
When driving around in the forward gears there were no problems? The fact that this is only happening in reverse is definitely narrowing it down to the reverse gears. Take a few pics of the cover....
The Dana doesn't use the Pinion support bearing. I would expect Larry there was noise when you lost that bearing. The thing that is making this a difficult diagnoses is the fact that it moves under...
I don't see anything that indicates the trans has damage severe enough to stop it from moving in reverse. I cannot see the counter shaft gear however. The damage to the teeth in the reverse area is...
Correct Scott, the input gear or "Input Shaft" is the gear closest to the engine. In the rear of the trans the large gear with straight teeth is the First and Reverse Gear. This link will help. Click...
I do see that tooth TJ. I also don't see anything that would prevent reverse. The transmission has been shifted once or twice no question about it! Lots of wear on the clutching teeth. If that is a...
Scott can you take a picture up close of the gears?
Yes, they are in the cover. https://www.kaiserwillys.com/diagram/cj-3a-diagrams/transmission-diagrams-willys-cj-3a/t-90-transmission-top-shifter/transmission-top-shifter Item 4. I am beginning to...
gm is way too kind. I am heading for the oldest in the business however!
Scott, this could be something you might be able to see before you pull the transmission. Drain the lube and pull the...
You are an hour away Scott. If you need help, we will try and figure it out!
Scott you have done a pretty good job of pinning it down. If it is fine in all gears except reverse, as long as it is shifting all the way into reverse, I think you have it figured out.
If it goes into first without any trouble, it sounds like the teeth are busted on the reverse idler and/or the idler mating side of the 1st / reverse gear.
Before I assumed transmission damage...
