It sounds like the 99 Grand Prix has slippage in the reverse band, or a stopped fluid path. Changing the transmission fluid and filter could help, if not then the transmission needs to be checked by a transmission since the band is inside of it.

Additionally, inspect the throttle linkage for proper adjustment and ensure the kickdown switch is functioning correctly. If these aspects seem fine, it may be necessary to have the transmission diagnosed by a professional for internal issues.
