      2021 GMC Elevation, Rock Ridge package. The 10L80E idler gear failed while I was on the highway, complete loss of gearbox operation. Doing some research online dealing with this specific failure I soo there are many of them happening now. Is there a GM TSB out on this repair or is it left to the Dealer. I am concerned with debris from the gear failure getting into my transmission and damaging the clutch packs, bands other bearings and the Torque converter if just the idler gear is replaced.
