It is usually controlled by a shift cable. Have someone move through the gears while watching the cable at the trans.
The cable could be loose, or a bracket.
Check fluid level in trans, engine running, in park and trans should be at operating temp.
If you do not see any problems with the cable or fluid level, then have a trans shop check it out.
