My 96 Plymouth Grand Voyager was stalling at all stops, after it was driving 10 or 15 minutes. Its like its stuck in high gear and won't come out. Now when I shift into gear it just stalls. Reverse , drive , 3, L there all the same . Any ideas on the problem, can I repair it myself? Thank You !

Your transmissions torque converter is likely "locked" on and needs replaced.
Unless you have experience with transmission repairs, you won't be able to tackle this on your own.
Have the symptoms diagnosed by a shop in your area and get some written estimates.
