I've got a G3 with a disintegrated speedometer drive gear. without it the speedometer won't work and the transmission doesn't shift into overdrive. This problem started when the radiator leaked coolant into the tranny fluid. The biggest part of the problem is that the part is only listed as part of a five hundred dollar package of parts from GM. But price is only part of the problem since all the dealers say the over priced package is no longer available. The part number for the gear is 90086219. I have found this part listed in europe for Opels and Vauxhal cars. I called GM assistance and got no assistance. If anyone knows of the part, or a source for spares from a wrecked G3 or Chevy Aveo which is interchangeable please let me know.
