Fixing a part requires you to just order a replacement, and once you take apart the car and put the part in, you then need to tell the cars electronics to accept the part as part of its diagonistics or it wont fucking start, even if everything else is fine.

Yea that’s nearly 100% untrue, though. TPMS sensors can be a little weird but no one is changing tires themselves, only whole wheels for summer/winter.
Brakes, sparkplugs, tierods, suspension, all oils, many sound systems and/or parts thereof, filters, batteries, and even a whole headlight assembly are all things you don’t need to tell the car about. I put a backup camera in my car and it just figured it out all on it’s own since there was technically an option for it, and I wasn’t even using an OEM camera. And the car usually doesn’t even know what’s wrong but if there IS a code you can just use an OBD2 reader, they aren’t exactly expensive and they’re super easy to use.
You either have no idea what you’re talking about or are a mechanic that I’m glad I’m not taking my vehicle to. My 2015 BRZ that has literally none of that, not even TPMS sensors(I know 2015 is not that new anymore but people have been saying this shit for decades). This is exactly why I show people how it works, so that they can understand that it’s not that hard or complicated.
P.S.: if it’s a German vehicle just shoot yourself, it’ll be a much less painful experience than realizing that a bunch of high-paid engineers with great reputations among the laypeople are really just the dumbest motherfuckers on the planet. Also less physically painful, too. You can still do the work, they just put everything in terrible places and use bolts that have needlessly unique and more fragile heads. Fuck you, VW, you idiots.

I’m talking about my own woes with the cars that I have, roughly 2005-2010ish. My current is an automatic with a manual gearbox in the background driven by an RTOS. Getting diagnostics out and putting parts in are exactly as I described above.
It sounds like the car’s you deal with are fairly modern then, and it actually gives me hope to see that the newer stuff allows for more plug-n-play tech, since I was envisioning pure vendor lock down for the newer stuff.

I’m sorry I don’t follow what you’re saying with the transmission thing. Like, I do, but I don’t know what car you have or if that’s stock or anything but if you’re talking specifically some kind of highly specialized transmission then ok, but you led with saying that it’s every part in the car.
Ultimately, there’s just no possible way for a car to actually know 99% of what you’re gunna do to it even if they tried without astronomically expensive sensors and RFID chips and a whole lot of other stuff. The only thing that can really confuse them is doing stuff like completely removing the air filter so there’s too much air(which actually hurts performance most of the time anyway) or changing the timing to where it’d be running like garbage anyway. But oh boy can you still fuck up a lot of stuff without the car having a single clue that it’s about to fuckin’ die. Hell, you could set the toe angle to 10deg and put the wrong brake pads in backwards and it wouldn’t even notice.
Fun note: On a 2018 Jetta I had to make spacers for the rear brake caliper because we tried FOUR calipers and they were all wrong, ending up with something that was the right diameter but the wrong offset. The weekend was over and we just had to get it done, but it still works fine years later. Never buy a VW, they are just dogshit and a massive pain in the ass.

An AMT, a clutchless manual. They were in that sweet spot of semi-automatic cars before transmission went fully auto
