Service bulletin G-208448
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

14614 - SERVICE UPDATE. REPLACE SUSPECT TRANSMISSIONS ON SUSPECT VEHICLES EQUIPPED WITH AUTOMATIC TRANSMISSION (RPO MYC). THESE VEHICLES MAY HAVE A TRANSMISSION-DURABILITY ISSUE DUE TO IMPROPERLY HEAT TREATED LONG-PINION GEARS, WHICH MAY HAVE BEEN MANUFACTURED BELOW SPECIFICATION FOR SURFACE HARDNESS. OVER TIME, THE GEAR MAY BEGIN TO YIELD AND THEN BREAK, WHICH CAN CAUSE GEAR TEETH TO BECOME DETACHED. IF THIS OCCURS, TRANSMISSION NOISE MAY RESULT, AND THE DRIVER COULD EXPERIENCE REDUCED VEHICLE MOBILITY. A TOTAL OF EIGHT VEHICLES ARE INVOLVED.
