Transmission fluid pouring out

I’ve been having transmission problems for the last year with this thing. It started getting worse and discovered the bolts were over tightened. After a bit the transmission would not get out of first, Car still moves but rpm's would just climb and not shift, so me and a friend replaced the Transmission with an 05 neon I bought as a parts car. I bought this thing with no starter, no battery, and no key, so we weren’t sure how many miles were on it (dumb idea I know). But we did the transmission swap and after 4 consecutive days of attempting to do this transmission swap we finally finished and got it in. Started out good, no leaks, shifting fine, perfecto! Well a leak appeared again and after someone told me their friend had a garage and would fix it he told me to change the pan gasket. I bought one and took it back to him and he did it for me. Since, it’s practically pouring out from somewhere I cannot locate. The under body is coated with it, it’s caked in crevasses under the 2 hose lines going into the transmission, and almost everyday I need to put like 2-3 quarts if fluid in it to go anywhere! It’s got to be leaking driver side somewhere but I do not know where and I’m fed up trusting people to fix it but I don’t have the money for an actual garage. It’s constantly low to the point it’s slipping and not allowing it to go into gear (which almost got me killed yesterday when it didn’t wanna move out of an intersection). It leaks the most while sitting and but also while driving, I know that by the puddle stains all over outside my apartment and when I’m driving in the rain I think it drips and my tire catches some of it cause I shouldn’t be feeling like I’m in Mario kart drifting turns. Before this thing kills me can anyone help me identify where the HE** it’s leaking from.
(Also unrelated issue-maybe)
After 70 mph the car has a serious death wobble, literally feels like 1, if not all 4, are going to fly off my car. I’m told my bearings are fine, control arms, tie rod ends, axles, balance, air pressure, etc. Are fine. So then why does it shake so violently? Serious help needed here! If need be to get a hold of me immediately.
