Actually your car has no transmission dipstick...
There is a red fill cap on the transmission bell housing under the brake master cylinder. You'll have to look real hard to see it. There is also a bolt on the passenger side of the transmission that you remove to check the level.
You have to fill the oil from the fill cap until it runs out of the bolt hole. Don't ask me why GM did this on a lot of their cars...
