Looking at the procedure, I would recommend taking this vehicle to a Saab dealership for new transmission fluid.
There are 18 steps to changing it. It's more than just draining it and filling it back up. So unless you have a service manual and the tools to do this job, it may be best to let the professionals do it.
It's not worth the chance of possible damage.
