tranny fluid

My and husband and I bought a 2000 Dodge grand caravan on feb. 16 2004 at Gaint Dodge car dealership. So only had the caravan for about a week. First when we went to get a sticker it didn't past the emergency brake didn't work. We did bring it right the dealership and they did fix the brake and we did get the sticker. Yesterday I went out to start my car in the morning to warm up. It ran for about 10 to 15 min. I noticed a little puddle of red fluid. I told my husband and he said that is tranny fluid. This morning I looked under the car to make sure that there was no stainsof any kind before i started my car to warm up this morning. It ran for about 10 min. I went out to the car and there was tranny fluid on the ground again. It sames to only leak tranny fluid when the car is in park. I just look under the car and it is not leak tranny fluid the (car is is not on). I'm going to call the dealership to tell them about this problem. Can anyone tell what the problem could be.

Where is the leak? If the puddle is just inside the passenger-side fron wheel it could very well be the power steering pump. If so, it's a much easier, cheaper fix.

I had the same problom with mine and it ended up being the tranny cooling lines that run to tha radiator, i brought it in and they replaced them with a updated set that use differnt type of clamps and rubber hoses.
