Default Anybody changed the auto trans fluid despite manual saying no?

Considering that it's a sealed transmission, I know it's not recommended to touch it. However for those that plan to keep the car for a long time I believe that fluids should be replaced to ensure the drivetrain's longevity.

So has anybody changed the automatic trans fluid even though it is "not required"? Was wondering how the transmission ran after the fluid change.

It is physically impossible to change a significant amount of the fluid

It baffles me on why people continue to want to go against the manufacturer's recommendations on this.

I did search previous posts (whether or not to it is possible to change it), I know that the manual states that it's lifetime (as there are recommendations for BMWs, etc etc), I know it is not a DIY project (requires the machine that transfers fluid at a specific temp while running).
All I am asking is if someone has actually done the fluid replacement and how it drove afterwards. Thanks all for responding.

Aren't most cars now equipped with 100,000 mile tranny fluid?

the only reason why i would even attempt to change it is because the canadian manual says change at 100k. but since im not there yet, im not that worried about trying to change it

Can you enlighten us how you changed it, given nobody has yet provided any method by which it's even physically possible to get half the fluid out, let alone all of it?

The nearest I've seen to a "change" was people who pulled the drain plug, got about 15-20% of the fluid out, then refilled it.

where do you hook the machine up to, exactly?

Might want to point out to him the page in the owners manual where it explicitly tells you the transmission does not require service, ever, and that it's a sealed unit.

Yeah... lots of dealers also offer "engine cleaning" every 10-15k which isn't called for in the owners manual either. Ditto changing your differential fluid which is never called for in scheduled service.

They're more than happy to charge for plenty of things the car doesn't actually need, it's almost entirely profit for them.
