my sebring 1997 will not drive when i put it into 'drive'. motor runs fine.

my sebring 1997 suddenly had a problem with the transmission. Before a stop light, it seemed as if it wend into gear. the motor stopped. only starting it in neutral and giving some gas i could get it going. it seemed ok after that but then on the road it seemed it was switching gears without reason.
Then the car stopped complete. When it was brought home i fixed the engine by replacing the crank censor. This was hard to do and i was glad the motor worked again. I thought that was the whole problem. But the car will not drive. It drove just slow 10 meters and quit. No forward or reverse.
When put into gear (drive) i also hear a noise i never heard before.
Is there a way to check what it is? The car service who tried to fix my car, read codes but also cleared the code so i have no idea about the codes.
