The reluctor and speed sensor can be purchased from PATC Transmissions. Yes, you just replace your factory speed sensor plug with the new one. If your car was originally equipped with a 4L60E then the speedometer will work with no tuning. If your car was originally equipped with a T56 then you will need to have the PCM calibrated in order for the speedometer to read correctly.

i bought my sensor and ring on Monday from Speedinc. Part numbers are
GM8655291(sensor)
GM8655315(Drive sensor rotor)
you will also need to get the plug for the wiring, i got mine at NAPA for $18
