the unit behind MX1; the 1984 transmission identification page also lists it, but the 3 speed automatic was not offered in 1984

GM Heritage factory kit — 1982 Chevrolet Camaro, p.8.
GM Heritage factory kit — 1983 Chevrolet Camaro, p.7.

El Camino — fifth generation (1983–1987)

1987 Single-source

With LB4; the 1987 order guide (p.45) sells a 3 speed automatic as standard without printing its code; MV9 rests only on one VIN legend page of unclear provenance, page 13 of the 1987 kit text (chevrolet/1987-Chevrolet-El-Camino.txt), in the kit's restoration section, which also gives the LB4 as a 173 cu in TBI V6 and lists two different 4 speed overdrives where the guide sells one; that page is not counted as a factory citation

This page aggregates every documented appearance of MV9 in the Chevrolet reference. Confidence and citations are shown per application — the same code can be better documented in one year than another.
