Hello!
Not sure if someone still read this topic, but what I understand that "C" means - Automatic transmission adapted to different engine variants. But than what means "A"??? I have 2003 saab 9-5 aero with FA57C02 transmission and because of accident (fedex truck hit my car on the street parking) I have to replace the transmission. So I found one FA57A08. Some people say that the differences are gear rotation, other people that is the year build. Any one can help me? I need to make sure that transmission will fit on my car. The transmission is coming from 2004 saab 9-5 arc/liner

C-transmissions can handle higher torque and are installed in Aero-models. A-transmissions are the standard transmissions you will find in the low-torque models.
FA57C01 was introdused in 2002 Aeromodels, and was soon replaced with C03 which had a better valvehousing. In 2003 came the FA57C02 with paddles on the steeringwheel, also replaced with C04 with a better valvehousing.
In your case you have to find a FA57C02 or even better, a FA57C04 transmission for your car. An A-transmission in your car will not last so long, depending on your driving habits, of course

Sounds like true. Anyone replace FA57C02 by FA57C04. Is any mechanical fitting issue or software problems? I would like to put FA57C04 in together with matching TCM to avoid problems bit dont know what ECU reaction for different TCM will be?
