how to drain and replace transmision fluid and filter in sealed 2003 malibu

I believe that trans still has a pan and you would need to drop the pan to drain the fluid and change the filter. There is a small plug in the passenger side of the axle tube to check the fluid level. I don;t recall where you fill the thing from though. Even if you can get it up in the air it isn't exactly a fun job. It's been many years since I've had to do it.

Great-thanks-fill tube is under the cross over pipe-drivers side///
