check the fluid ( reg oil 5 w 30 or 10 w 30 )by checking the check point when the car is cold ( not run for 6 hours) on the passenger side bold under the exhaust manifold. I think it is 19 mm. you should have 3 quarts. Also there is a filter on the rear cover that has a magnetic trap that needs to be replaced. Also you need the rear gasket if you are taking that panel off. dont reuse paper gaskets! they will always fail.

in that transmission shift gear first, then give gas. it is not very forgiving.

that is what they consider safe mode for those transmissions, they are a very smart electronic transmission it does that so you dont ruin the trans.
It has detected a problem and you must take it to a tech and have the codes pulled, could be as simple as a sensor or solenoid pack

SOURCE: I need an engine diagram for a 1995 saab 900 se V6

A SAAB dealer should be able to print one out for you. BTW that engine is practically identical to the V6 used in a caddy Catera, and Saturn Ion. Those diagrams would be the same, so you might want to search that also.
