- 2015, 2017 Factory-verified
GM Authority's 2016 RPO-level changes list a body-color grille TC7 among the 2016 deletions and the 2018 fleet guide omits TC7; 2017 rests on the shared 2017 manual alone.
This page aggregates every documented appearance of TC7 in the Chevrolet reference. Confidence and citations are shown per application — the same code can be better documented in one year than another.
