I have recently purchased a 2008 Saab 9-3 2.0 with an Aisin 55 (or Aisin AF33) 5 speed automatic transmission. I am confident the transmission fluid was not changed until I changed it at 125,700 miles. The car seems to shift well in all gears. At the time the sample was collected I did 3 drain and fills of the transmission with Toyota IV ATF. In the couple hundred miles since then, the car continues to shift well. There was no burnt smell to the oil. [img][IMG]http://i1134.photobucket.com/albums/m608/LeefromMaine/engineoil.png[/img][/img] Thanks for any thoughts.
