Basically, the inside diameter of the washer became smaller than the diameter of the threads on the drain plug. The outside diameter of the washer expanded out, while the inside diameter expanded inward from being crushed too much. Hope this makes sense.

Not a big deal, but I went ahead and ordered a new drain plug for next time. I had to put the old drain plug back on (along with the previously twice-crushed washer) since it was gonna take a few days for the new drain plug to arrive. I've checked it a few times after driving around for a few weeks now, its not leaking.. even with the thrice-used washer.
Thank you, I really appreciate your response. I will order a new drain plug next time I switch the fluids to play it safe.

Did the swap this weekend.

When I was filling the transmission I was surprised to find that I put in ~2.5L before the oil started leaking out. It did leak a good amount (because I didn't notice it at first, since it follows the lines of the transmission and a good amount was on the little grid fins on the side of the transmission. Still, I think this happened because my garage floor is not as level as I thought it was. Car was at an angle so I could get under it easier such that the rear right was the lowest point. All of the jackstands were at equal heights though.

The shifter seems to be what I would call notchier (not sure what people mean when they say notchy), I can feel a little of resistance going into each gear before it pops into gear. No grinding or anything like that. Other times though it is really smooth. This is with Motul 300.

Is there any harm to the transmission to have ~0.3 L too much oil? If so what's the best way to leak out a small amount to get it back closer to 2.2L? I feel like I should have just tried to put 2.2L in and stopped even if it didn't leak, but I'm not even sure if the bottles have exactly 1 L in each bottle. Was thinking about getting a pump and syphoning out ~0.2 to 0.25 L to make sure that its not underfilled. I've heard that you can just level the car and let it leak out the top hole, but I'm not sure what the best way to level the car on both axes is.

I'm really shocked I could get 2.5 L in it, I would have thought there would be less tolerance for error when filling it up. I really wish this car just had a dipstick like the WRX so I could know for sure.

I kept filling and waiting spill over. When it didnt happen past 2.5, I got suspicious and stopped filling. I was definitely closer to 2.75L. Didn't have a way to get it out without opening the drain plug so I left it in because I didn't want to over drain it. After driving , so far so good, but I worry that maybe thermal expansion will cause the tranny to explode. I have no actual evidence this would happen, but I think about the one time I put a beer in the freezer. Opposite temps but same idea.

Here is an update.

After reassessing the situation, I think I had about 2.45L in the transmission. Ended up jacking up the car again. This time didn't angle the car in the garage. Took the fill plug out and immediately some oil dripped out.

I used a bubble level app on my Android phone to see how level the car was front to rear. Found a good place to place the level was on the main ridge of the transmission (going front to rear). Kept jacking up the rear of the car until it was level to within 0.1 degree. Can't believe how unlevel the floor was. Also, am wondering if the transmission is even level to the cars frame. When I did this, more fluid came out. Let it drip till it stopped, and measured what I took out as ~200mL. Pretty close now to the spec (~2.25L). Plugged it back up and took it for a drive... Much less notchy and much smoother. Still, in my judgement, about the same as stock. However my car is used, so not sure if the previous owner had stock fluid in it or not. So I can't say I'd recommend Motul, but I'm just glad my car is feeling better again. It is still slightly notchier occasionally, especially when cold, but draining the excess fluid made a huge difference. Highly recommended!

Wanted to share my experience. I think this is a pretty common issue as I've read about it on the internet and this forum a few times. Hopefully this helps someone.

Have a look at this. I caught some grief for being too anal about it but the CAR being level matters when doing the tranny fluid fill.
