I used to think the same thing but after tons of reading, there’s several theories which I can see could be possible. I guess over time (without regularly maintaining fluid changes) the clutch packs, hydraulics, and all the moving parts in your transmission ends up wearing out due to friction etc and they end up having excessive gunk build up that sits in the bottom of the pan or in crevices of the transmission and once you change the fluid the newly introduced fluid picks up the gunk and ends up clogging the valve body or pistons in the transmission. There’s that theory and another one being that the transmission may be toast to the point where all that gunk is most likely what’s holding all the moving parts together to they’re “acceptable tolerance range” that once those fluids get washed away the new fluid will now be too thin to have the moving parts within their proper tolerance range because of all the wear in the transmission. Something like that lol. I do feel like it’s true, cause when I had transmission problems on my 1st gen the first time, I tried changing the fluid and it just came worst. But the transmission was already toast and the fluid I drained out smelled beyond burnt so I feel like it would probably do the same for a transmission that is still working but on its way out. I feel like we need to maintain our transmission before they get to the point of making its way out lol.
And The Car Care Nut is an awesome channel!
Great video! Thank you.
Braddah that’s sr5 with trd off road badge?
If you know what you looking for when buying 4Runners used. Can low ball the up-badgers lol
Yeah lol
It doesn’t make sense that changing the fluid would ever make any problems. 🤷♂️
