2000 Grand Prix SE

Hi all...My 2000 Pontiac Grand Prix SE has 107K miles on it.
Recently, at about 1800 RPM the tachometer begins to fluctuate and the car feels like the transmission is slipping. I generally am on the highway when this happens and last night the RPMs where down around 1000 when crusing on the highway. THe car has power when i want it but this fluctuation makes me worry.
Any suggestions or comments?

Sounds like you have the beginnings of a problem with one of the primary ignition components. The primaries consist of the crank sensor, ignition module, half of the coil and all related wiring and connectors or even the PCM. It may have to get a little worse to be able to find the problem.

If it's under warranty, just make it their problem. It won't be easy to find they'll have to try.
