2005 suburban speedometer does not work right, gets stuck at different speeds and I have already changed the pickup on the transmission, what else can be wrong?

Is this a digital or analogue type gauge?

Its analogue, also we have noticed that the fuel gage has been giving funny readings.
It will be 3/4 full, then almost empty, then close to full.

Sorry been a bit ill last day or so, if the pick up has been replaced and you are still having a problem, and being an analogue type gauge, I would be thinking that it is in the speedo head or a problem with a small crack in the printed circuit board on the instrument cluster, you may be able to trace the wiring on the board with a multimeter to check any high resistance through the circuit board that can be causing these erratic readings.
