Growling automatic transmission

Another question - please help.

I changed the transmission fluid on my 5-speed automatic - twice - no flushing, but 7 liters twice with ZF5 Lifeguard to get as much of the old oil out as possible. Did it a week ago and has driven approx 200 km since the change.

However, my transmission "growls" a little. Not consistently, but some days with slight growl and a light vibration which can be felt in the entire car. And it feels "lazy". Other days it runs smoothly, silent and no lazyness.

Any ideas what it could be? Will it dissapear eventually or is a sign of a problem that will get worse? Did not notice this problem before the change but back then the car was new to me, and I may not have noticed as I was occupied with other improvements and servicetasks....

Car has done 190k km and problably the first transmission fluid change ever done.
 
I would like to change my auto box fluid but this is a worry :|
I did read somewhere that you have to go through quite a few things once the oil has been changed

After the change? I know there is a procedure for changing - temperature of fluid, run gearbox through all gears etc. But after? Do you have this info to share?

In Practical classics last month, they show how to do an oil change on a BMW box. He gets the warm, not hot then jacks the car up and says to keep it level, changes the oil, filter and clean the magnets.
Put in the same amount of oil as you take out, then run the box through the gears.
