If the transmission is a manual, when you shift you should release pressure on the accelerator when you depress the clutch, this closes the throttle and the engine speed drops. If you are up shifting, the RPM needs to drop for the higher gear anyways so when you let the clutch up the RPM has dropped and the clutch engages smoothly.

If the transmission is an automatic, you do not need to easy up on the accelerator when it shifts, the transmission shifts so quickly that the RPM just drops even though you are still depressing the accelerator.

Later model cars retard the ignition timing so the shift is softer on the transmission.
