Strange question regarding licences

Hi if anyone might know the answer to this it would be amazing. I'm learning in an automatic car that we already own but if pass in that I know I'll only be able to drive automatics until I do another test for manual vehicles, my question is this.

Say I've passed my automatic practical test and then I do do my manual test. If I fail the manual test, for example I get majors or something like this.l, do I lose my licence or can I still drive automatic vehicles? Thanks :)
