The transmission is messed up, try playing between neutral/reverse and drive, my old Hyundai excel did that and the transmission did a weird sound then went back OK, but not for long.
Recommended to change it.
it will drive but when in reverse it wont move

Your shift linkage may have slipped or become loose. Check your linkage.
Hoe a train moves.
For the Reverse problem, you could have low transmission fluid, or a bad transmission. For starting in drive, just about every modern car will not start when the transmission is in gear. They will only start in Park or Neutral. This is a safety feature to prevent the car from taking off into someone or something when started.
It needs to be in park or neutral to start. All cars have a "safety" switch which prevents starting in gear.
Shift linkage may need to be adjusted?
does it shift into reverse and wont drive? if so its your tranny it needs to be replaced
i cannot shift from 3 to reverse my cable line for the shifting is disconnected and don't know where it suppose to go
No your car just wont come out of park.
You are probably low on transmission fluids
Sounds like starter or neutral switch to me.
