what exactly is the flush procedure?
warm up car , drain fluid - about 3l should come out. then fill up again thru the fill tube below airbox.

Go for a drive - accel. to 60km/h then coast to almost 0. Do this approx 4-5times and you have "relearnt" your transmission. This should get rid of most if not all shudders - ideally you will need to drain and fill again soon to guarantee all old fluid is out of gearbox ( some gets stuck up in the torque convertor etc)
