I have found that I enjoy my vehicles a LOT more when I just drive them and don't read forums about all the problems folks have with them. Forums, including this one, are great for a few things. Grins and keeping in touch with other folks who love the same vehicle you do is certainly one of them. Another great function of the forum(s) is to find how-to picotorials to maintenance tasks and repairs that you haven't done previously, to make sure you're identifying things correctly.
A couple caveats.. you have to know your personality type. If you're the type who looks for problems, thinks every little sound you hadn't noticed previously is probably indicative of a major repair (when usually, it's a bent brake shield, loose heat shield, or something else meaningless), or just generally a "worrier," forums are the road to hell. I can be one of those folks, but I'm aware of it and proceed accordingly.
You also have to know the internet and how folks work on it. There are a lot of people who "speak" (write) very glibly and sound quite knowledgeable, but in reality are just internet jockeys who just regurgitate stuff they've read before but have no real world experience with what is being discussed. Even worse, they write in such an intelligent manner that the sometimes incorrect (and sometimes downright wrong and dangerous) information they post is taken as truth by others without any background knowledge and then further dispersed. Vicious cycle. On the other end of the spectrum are folks who TRULY know their stuff and have tons of actual hands-on experience DOING repairs and maintenance, some professionally and highly respected, but either can't write well or competely, or just don't care or take the time to do so. Posts can be borderline illiterate, so folks discount their input wrongly. OF COURSE, there's lots of overlap.. extremely literate true experts, and a vast number if illiterate wannabes.
THE challenge is in learning enough background info to be able to make good decisions as to which posts to believe, and which posts to discount. As with all things, even then, it's best to verify. If you read it in a forum, treat it as an idea. It's up to YOU to decide whether that idea is a fact, an opinion, a good idea, a bad idea, or an outright untruth. Therein lies the rub.
My opinion to the O.P.? There's absolutely nothing wrong with your transmission, and you are shifting with too much force. Now... which type of poster am I?
