My 2003 Saturn in the owner's manual recommended ATF also. I had the transmission fluid changed a while back. The service manager recommended a Valvoline product rather than ATF. I had the fluid changed and it works okay but it seems to shift a little slower especially in cold weather.
Maybe all they had when they came out with these manual transmissions was ATF. But if it worked okay and a person was able to get several years of service and 100,000, 200,000 miles out of the vehicle, that is good service. Sure, maybe better products are better today than the ATF at the time. I am not so sure those products are really better however.
