If you've been leaking tranny fluid, the problem is the fluid is low!! Add some of the recommended fluid ASAP!! I forget the exact recommended fluid but make sure you get the right stuff, not just any old ATF!! Dealership will be able to tell you and I'm sure you could get the answer on this site. When I've done my wifes I've used stuff from the stealership. I think it's like +4 or +5 or some special mopar stuff. Whatever it is, use the right stuff!!

Fill it NOW, because you'll smoke your tranny running like this for long!!

And still change the fluid/filter as soon as you have the money!! Also, don't over-fill...that's also bad!! You're going to want to find the leak and fix that as well. DO NOT put any stop-leak stuff in your tranny unless you feel like gettin a new tranny very soon!
