Automatic Transmission problems of the 1997 Saturn SC1

I bought my Saturn Sc1 series 1997 at 83,000 miles. The service engine light was on. Had it checked at auto zone, second gear to ratio was off, a few thousand miles later, 90,000 I lost reverse. I drove without reverse for 2 years until I could afford to get it fixed. The transmission guy told me that the nut/bolt that holds the gears twisted off cracked the shell of the transmission. Not good at all, I had to put a full bottle of tranny fluid in it 2-3 times a week for almost 2 years. And had to pay for it myself as it was a defect of the maker, not mine. I will never buy another Saturn. Ever. Sad thing is, I'm still paying on it.

Vehicle stalls when downshifting. Also, there is no horn, and headlights will not come on .
