Yes, This is what the TransparentColor params are used for as you have
noticed.
Which version of GeoServer are you using?

Which values did you try? 000000?
If black doesn't become transparent even after configuring these parameters
properly, a possible cause could be on your data (can you share some more
info on them?).
Does your mosaic is made on top of datasets having overviews?
If affirmative, how did you create overviews? A possible issue could be if
you have not-zeros along the datasets (as an instance, zero in the original
images transformed as non zero when creating overviews with some types of
interpolation having no-data unspecified).
Cheers,
Daniele
