Hello everyone. Have a problem with my automatic. Own a 9-3 year 03. The following: Between 70-80 hm/h and this in certain situations e.g. when I give off light gas on a small slope the gearbox starts to vibrate and when I walk away from the gas it is gone. This happens because the automatic changes from 75 km/h to the 5th gear and although the speed is at 1600-1700 rpm, the automatic still stays on the 5th gear instead of switching to the 4th gear. So the car runs un tertourig. This can be noticed quite well when switching to the manual circuit. With little gas you notice that the car vibrates. The lower the speed drops and you still drive with the 5th gear the noises and the hum louder. I then had a software update for the transmission carried out. It drives better and more sporty but the problem is still there. I noticed in different forums that many have this problem and to an automatic transmission oil flushing guess the most solves the problem. Someone knows about it. Thank you
