RPM gauge

my 03 Sierra. the rpm gauge started to bop around. It will be working fine then just drop to 0. when cruising at 55mph the rpm gauge will read 1000rpm. So when I kick it down the gauge may jump up to 2000rpm but it should be like 4-5000rpms.
Any one have any knowledge on this issue? Pleas help dealer bound on Monday.
