Is it normal to not be able to Move your car for a few seconds after you change your transmission fluid

Yes, yes and yes, and we have an open question where you told me to just clean it with brake cleaner. I asked you if I should be worried about anything that got up inside and you didn't answer.

Thanks Roy! I fixed it, simple mistake. Basically, I looked up my fluid capacity. So I read four quarts and I was under the impression that was the entirety of the system. So, while my pan was being taken on and off from me re-threading female threads and messing with the torx screw, I lost much more than 4 quarts. So last night, I put in my four new quarts. I then waited 40 minutes to let it drip down, I checked my level while running in neutral and it was reading correct level. What I didn't realize is that 40 min wasn't enough. It was an inaccurate reading. So instead of 4 quarts, I added 3 more quarts so 7 total. She's running beautifully now. Basically I didn't realize that there was more than four quarts, so last night when I was experiencing this problem, it didn't even cross my mind. I thought I added four quarts, I checked my level (inaccurate reading) so I thought any more fluid would flood it.
When I spoke with my father this morning he explained the situation

Aside from my brand new tire already getting punctured, the days turning out okay. Thanks as always
