Angry Need HELP, Transmission, Torque Converter.

Woke up and went out side to start the car and notice tranny fluid on the ground, but still went to start the engine. After I did I went and looked under the car, fluid was pouring out where the torque converter is. Then I shut the car off and fluid came out at small drops at a time. Someone said it might be from the front seal, but it pours out like it's from the converter. I'm 17 have a job at BestBuy and go to school, so I really need this car to work. I know a friend who's dad has a Mech. Shop, and trying to get a hold of him to get it fixed. What would you think the price might be or if you have any solutions.

P.S. I got this car for free, this is really the only thing that has went wrong. Also the only problem with the transmission before was some vaccum leaks. Another thing, last night when I was almost to my house I heard a weird Whinning which sounded like it was in the car, not sure if that was the torque converter or what.

The torque converter has a drain plug. It would be unusual, but not impossible, that the drain plug just started leaking. There is a small aluminum seal that goes on the drain plug, some times a mechanic will forget to remove the old seal during a trans service, and this can cause a leak, but usually it will start leaking right away after the work, not a long time afterwards.
The front pump could be the problem as well, either the seal is just bad, or a problem with the pump itself.
To reseal or replace the front pump involves removing the transmission, which takes several hours of labor. Resealing the front pump once the transmission is removed is a couple more. If it just needs front pump seals, the parts are pretty cheap.
I'd recommend putting the car on a lift and rotating the engine through by hand (large socket and long breaker bar on the bolt on the front of the engine) while someone inspects the converter for damage and also to look for/at the drain plug on the converter. If it looks more like the leak is at the front of the transmission case itself (behind the converter) that would suggest the front pump has failed or has leaking seals.

Don't forget to add trans fluid if you plan to drive it to the shop!! Better off calling a flatbed towtruck.

Are you sure its from the TC and not the pan. The tranny fluid pan has a gasket and you will find some horror stories about them leaking on this forum.
I too think it might be the TC drain plug just coming off completely. or its really loose. Check that plug by having someone maually turn the engine while you guide them to the point where you can clearly see the TC drain plug.
I hope its the plug this will be a cheap and fast fix.
You might have to put the front end on the ramps.

Please take proper safety precautions when you are under the car.
I sincerely wish you all the best and hope its nothing major.
