Just flushed my auto box with this stuff

Took 22ltrs to turn it back to cherry red! however the difference is like night and day, much smoother now.
Cost £4.30 a ltr
No filters in the box to change
I was going to have the gearbox software updated and adaptions but after reading a few post from people who said their gearbox changed awful and started to flare between 2nd and 3rd afterwards I decided not to bother as mines nice and smooth anyway.
