Hi this is my first magna after owning just bout evey thing else. being front wheel drive should i run an auto trans cooler? will it effect my AC if i run one in front of it. can i run one down below the trans level?

Definitly yes, especially where you live. after market or 2nd gen OK.
mount in front of condensor down behind bumper works for TS/TR type.
no harm done to plumb it in line with built in radiator tranny cooler either.
regular tranny services are recommended for magnas too.
