Help! Trans problem in Belize 1999 Lincoln Cont

When I was in the USA the front seal on the trans started leaking. Had the seal and torgue converter installed new. Then its change hard from 1th to 2th gear. Took it back to shop and they check it and said it was not coming from the work that they did so I drove it back to Belize. It has been two months and this morning I started the engine and it sounded like it went into a gear when it was in Park. I shifted to reverse and there was no reverse but sounded like it wanted to go into reverse. Got a push backward and shifted into Drive and it went forward but slower than usual. Now the trans has no reverse and when I shift to neutral it is Drive instead of neutral. Anybody got any ideas for a troubled 1999 Lincoln Cont. in Belize. Also what kinds of Trans will work in this Lincoln.
Don't need answer now, got rid of that thing!
