Yea, it stirs up the crap that's settled in the bottom of the oil pan
and sends it back through your tranny. I've heard of VW eurovan transmissions
dying not long after a flush.
I just change my fluid and clean out the pan, and replace the filter.
The drawback is that a simple fluid change doesn't change all the oil.
In the Eurovan about 40% is still in the torque converter.
So I change the fluid more often. That's useful for a eurovan
anyhow because their transmissions are a known weak point.
