Automatic Transmission Fluid Leaking from Cap itself

I guess maybe I should have specify the exact time of my Transmission fluid and filter changed, I did the changed back maybe 3 months ago and I don't really use the car much I was only very recent that I had to but after a few days of putting a new auto trans fluid I started getting small drip leak on my garage floor and when I checked, it looks like it was coming around from around the trans mission pan and so I thought since I put about 7 quarts of trans fluid per requirements I would have more left since it was only a drip that I was seeing under the car, but recently I drove it at about 200 miles going to and coming back home, the oil indicator light on my dashboard started blinking, so when I got home I added 1 quart of trans fluid then the light went away and I had to drive it again for another 200 miles and the oil indicator light on the dash started blinking again so I kept adding another fluid only this time I added 2 quarts, I didn't start noticing that the leak was now coming from the auto trans fluid cap, I didn't thinks that I was over filling the fluid because of the light indicator blinking and my first assumption was it was the trans fluid censing being low, every time I added trans fluid the light indicator on my dash goes away and that's the only reason I was adding more like right now prior to this question I just added 1 and half quarts of trans fluid and the light is Not blinking but the fluid is still gushing out of the cap after starting the engine and waiting for about 1-2 minutes, is there some kind of electronic that maybe is NOT working inside transmission to make that trans fluid over flow, I get what you are saying that maybe instead I was over filling, I just thought it was low on trans fluid because I was seeing trans fluid leak drip on my garage floor, if you still think that i'm over filling the fluid, what is that oil light indicator that keeps blinking on my dashboard and every time I added the trans fluid it goes away and I also check my regular oil level and its at a normal level and the color of the leak is pink just like the trans fluid that I kept adding. I would like to hear if there is any other thoughts.

Yes, I have seen that video on youtube many times a while back when I was looking to find the dipstick on that same car that I have, so are you saying that the reason my transmission fluid is leaking or over flowing is really just over fill, even after I explain how this happen from my previous post? This is just an assumption because you didn't exactly response to my second post.

Thank you for all the tips, the same day from my last post, I found the trans fluid drain plug and I let the fluid drain until it stops and put back the plug and closed it tight, then I drove it around, at first the oil indicator was still blinking but after awhile it stops and never came back and the also the trans fluid stop gushing out of the fill plug, As mention from my first post above, I did changed the O-ring on the Trans Fluid Fill Plug Cap a few times cause I thought I had the wrong size fit that I pick up from The Home Depot store but that didn't fix the fluid gushing, so right now it is no longer leaking from the fill plug cap and No Oil indicator light on my dashboard either and seems to be working fine, I guess CJ MEDEVAC above was right all a long that It was just over fill, thank you again, also just fyi. After draining some of that over fill trans fluid the engine sound seems to be much quieter than before and I think that's a good thing.
