Hello guys!
Here I am.
Finally I've changed trans. fluid

I bought Conoco Phillips Dexron VI as said before and new filter with gasket.
Well what can I say... I'm happy.
At this stage were used 7 quarts of fluid and after 300 km I'll change it again to renew.
Below is small photoreport as promised.
Below is magnet. Also as you may see there some small metal dust on it.
I washed up pallet and put magnet back...
