The difference is the complexity if I understand right.As well as a human factor of screwing up the fluid level etc. Just my thought.
Some things work better and longer without you poking them unnecessarily.
When I bought my X,it was sitting for a while and what my indy told me was,that the ATF is a dark jelly now and when he drove it,it wouldn't engage the 2 gear for a second and slam afterwards.Bad ATF,sludge what eve it was causing it,I don't know.
SOOO,make it shorter.They drained half of the ATF and refilled with new,I have no idea which brand etc,I have no idea if the filter was changed at that point.
After 600kms my Torque Convertor started shuddering.
I had a tranny rebuilt.
Conclusion,If you service something make sure you do it right,and the only way to do it right is following the manufacturer's literature and specs.
It was my first Auto box and still is,I had no idea how complex they are and how sensitive they can be to fluids,filter etc.
When the tranny was already rebuilt,I had some Filter whining due to an aftermarket filter,Filter needed to be changed.
I was filled with Dexron IV ATF because it was the only thing the shop carried.It took me 15 liters of right ATF to get as close to the full volume of right specs fluid.
Torque Converter needed to be rebuilt twice...valve body was rebuilt,but didn't meet the specs and aluminum casting part was replaced...
Why I write all this?
If you tranny isn't giving you headaches and you flush it,at least Do It Right with right Filter and Fluid,I see absolutely no point of saving $50– 100 bucks and getting wrong stuff in.
Am I wrong?

I know that a transmission is a sealed system, but on hydraulic machines, that are also sealed, the hydraulic fluid needs to be changed in a maintenance schedule. What would be the difference between both systems.
I'm not arguing, just trying to understand.
