Auto Transmission slips on 1998 Porsche Boxster

My 1998 Boxster slips in forward and revrse gears to the extent that the car will not move. Is there any repairs that can be done ?

If the Boxter has a manual transmission the clutch is worn out or something is broken in the drive train but most likely to be a worn out clutch. Similar if auto transmission equipped, either the transmission has failed or something has failed in the drive train.

sounds like the clutch is worn out or at least needs adjusting.
