Default RPM oscillation?? Diagnosis pls.

In 4th & 5th gears when going up slight inclines
@ ~ 1800 - 2000 RPM under constant throttle the RPM range varies between 50 & 100. I can hear the revs drop and come back repeatedly though I'm not modulating the trottle? No CELs or codes. Any suggestions? Thx.

possibly, if your RPMs are not moving in a similar manner to your speedo.
