Your transmission is either C5 (three speed ) or AOD (four speed with overdrive).
P-R-N-D-2-1  C5 selector.
P-R-N-D-D-1  AOD selector.
 Don't know what your problem is.

Could you amplify on your symptoms? If its a AOD you only have this problem in Drive or in Overdrive too? What's the transmission fluid like?

Could have a gearset failure. Get a high contrast towel, white will do, wipe the dipstick onto the towel. Any contamination? Smell burnt?

Wouldn't the selector for AOD be:

P-R-N-O-D-1
