General Motors has determined that certain 1992 C/K trucks, P30 trucks and G vans equipped with 4L80-E or 4L80-EHD electronic 4-speed automatic transmissions may have a transmission rear internal gear with an improper heat treat process.

Owner name and address data furnished will enable dealers to follow-up with owners involved in this campaign.
These listings may contain owner names and addresses obtained from State Motor Vehicle Registration Records.
