Who's wrong, Me or Toyota?

Im a toyota tech and servicing these overfill style transmissions is easy. And will shift better if done right then when brand new. Drain fluid with removing both the drain plug and overfill plug. Filling trans with new fluid and get fluid up to around 95° and open up the plug

I wasn't arguing about changing the oil in a BRZ/86 auto. My post was more of an off topic post. I was just noting that sealed boxes are now a thing. The very concept of a sealed box weirds me out.

Please see Apple laptops built after 2014.
Everything soldered onto the board, including the SSD.
Battery epoxied into the case.

Sure but for some reason I don't find that as strange as a sealed mechanical unit subject to mechanical wear and tear.

I got told the same thing by a salesman. I nodded my head and walked back to talk to tbe guy actually working on my car. He said it looked like it needed new fluid. So I told him to change the AT fluid, he told sales to charge me, and everyone one was happy!!! (Except the sales guy, but F- him)

That is the thing with transmissions though. Car guys as a whole tend to over change fluids in the belief they are making things better somehow when really they have not done a thing. There really isn't that much wear and tear where changing the oil will help. Unlike your engine oil where temperatures and pressures are much higher, you get shearing from the pistons, and fuel and carbon contamination the fluid in a modern tranny could indeed last the life of the car under normal operating conditions. I always chuckle when people say their tranny oil came out really black. What the hell did you put the poor thing through to turn the oil black? Now of course misuse or extremely heavy driving can cause issues that may break down the fluid but at that point the fluid itself isn't the problem whatever caused the contamination is. I can see more sealed units coming in the future and repairs will be to simply swap out the whole module.

Even "sealed" transmissions aren't sealed. There is ventilation to allow for pressure equalization, which in turn would allow for oxygen, water, dirt, and other stuff to (albeit very slowly) degrade the fluid. At some point, the fluid will have to be changed. Determining that requires inspection, and unfortunately it is increasingly trendy to "seal" the transmission, preventing inspection

I do Desktop Support for an IT firm and you are confused if you don't think computer parts suffer from wear and tear. The arms on HDDs snap off all the time. Batteries can only be charged so many times before they become useless. When a user has a bad hard drive or battery we would go broke handing out new laptops every single time. We just swap the parts and give the unit back

This is a car forum after all. I'm sure a lot of people here have no idea about computers and how wear and tear would apply to them, which would primarily be heat.

Heat is the mother of all problems. You could even say, we were all the product of the heat of the moment?

I am not confused. Maybe mistaken.
I implied ("Sure but for some reason") that I do not consider the "wearing out" of silicon in the same light. Hard drives, cooling fans and mechanical switches are mechanical; all other computer parts to the best of my knowledge ( and I do not claim this to be complete ) suffer from heat damage and atomic scale fatigue.
I am a mechanic by trade and although I haven't been paid to work on a car in decades it is probably why I consider sealed boxes weird.

"wearing out" of silicon is not that uncommon these days, when 1) density of elements on chip got too insane, 2) market changed to release frequent updated gadget versions so that many still replace it way sooner then even that shortened life may last.
Some 386 cpu i expect to be able to work just fine for 25+ years (if normal "wearables" are dealt with, like batteries, capacitors, mechanical stuff like in disks/coolers. Very latest intel/amd offerings of tenhs of millions of very densely packed elements in them? I wouldn't be very sure in them working completely glitchless 5 years from date of producing.

It reminds me length of life for over-engineered simple & robust german cars of past vs that of current crop designed to last way less. 30 years & million miles? No problems. Or 3-5 & 100K, just to pass warranty period with reasonable/acceptable count of repairs/recalls.

Take a look at Ptuning in Manassas. They won't give you the runaround and the prices will likely be as fair as possible. Letting them perform the service won't affect the warranty on your transmission as long as you keep the invoice and they use a suitable fluid. If anything happens to your transmission, it's likely to be after the warranty is up anyways!

Ptuning blew up one of my friends Scion TC's while he was running the TRD supercharger, blamed it on him saying it was his fault and then deleted all of his feedback he gave on their facebook page.
