1999 Saturn SL2, it has approximately 100,000 miles on it, and I just filled its fluid in its trannie three months ago, and its leaking, I didn't know it was doing this until I looked last night. Its not a stream of fluid because its low now. At first my father and I thought it could have been the speed sensor, because it stumbled all over itself trying to shift when it thought it needed to and it couldnt. So what could be wrong with my Car? Is it a seal? Or is it cracked? If it is the seal how much would that cost to get replaced?

Go to a parts store and purchase a lubricating system leak detecting dye and rent or borrow their black light. Put the dye into the transmission and drive it for a day or two and then use the black light to locate the leak. That's the best way to locate it. There's now way to locate a leak without looking at it.

When I poked my head under my car (cause its so low to the ground) I saw the fluid on the Tansmission so it was closer to me so I would say it was in the front Jacobandnickolas, and thank you Rivermikerat

He is correct. The dye will show where it is coming from. If it is closer to the front, check the cooling lines to the radiator first.

Just to add to this one you said you replaced the transmission fluid 3 months ago did you replaced the transmission filter also?If so did you make sure the filter is tight?A loose filter can leak a lot of fluid. If thats not leaking rivermikerat had a great idea transmission leak dye in fluid and a dye light will trace that leak down. Also you said you refilled the transmission does it shift normal now?

Um Saturntech9, I haven't refilled it yet, and im too scared to drive the dang thing in the fear of breaking it, my dad has not come up yet from Arlington to help me. And we did replace the filter, im not sure if it is tight. That might be it, now mind you it was not my father who put the filter on, we replaced the Air filter, Oil filter (and oil) and the Transmission's too. I'll have my Mom's boyfriend jack up my car tomorrow and have him look at it. And I will let you know. Thanks.

Check that spin on filter I have seen a lot of them leak from being loose. If you stopped driving as soon as the transmission started acting up then there is a good chance you saved the transmission by doing that. Keep us posted on what you find.
