Possible transmission issues 94 Jeep Laredo 5.2
 

HELP: 1994 Jeep Laredo 5.2 possible transmission problems...
Bought just 2 weeks ago. Soon as it was transferred drove across the road from courthouse to get air and came out to antifreeze leaking (huge green puddle) and bubbling out of the overflow. I did leave it running for about 10 minutes when this occured. Removed thermostat, problem solved. Go 5 more miles down the road and the transmission stopped pulling in all gears and died. Kept trying to start it and it when shifting into gears it would be real jumpy then die every few feet. Had it towed and changed transmission fluid and filters (transmission fluid smelled burnt and black, also had a lot metal shavings in trans pan). Drove like a dream for days. Then a week later it is hit or miss. It will shut off at a light or when coming to a stop and sometimes it don't. At times it idles rough too. So changed transmission fluid and filter again, this time it's a dark purple and not many metal shavings and thin layers of something like carbon laying in tray. Did this last night and ran perfect. However today it just wants to shut off when put in gear and will jerk. But it will eventually go. And I have to take it out of overdrive or it will die as soon as I put it in gear. If its in overdrive it will jump, stall, and act all kinds of crazy then quit on me. However reverse works like a charm, never have a problem when I am backing up.
Only light on is ABS and the gas light stays on all the time, and the gas gauge don't work either. I have also had to replace the battery the day I changed the transy filter for the first time.
I might have several problems going on, but any and all information is appreciated.
Please help!
