The 4 speed automatic 700R4 is introduced and was the only automatic available on V8 cars. It will be the only automatic available for the rest of the generation and will go on to recieve upgrading throughout the years. The T-5 5 speed manual was introduced and was the only manual transmission available on V8 cars also.

All Z28 hoods were switched from SMC to steel except the LU5 air induction hood. This would be the last year for this functional induction hood, only available on the Z28, which still featured opening flaps for a ram air-like effect. Charcoal was added as a wheel accent/valance color. The gearshift indicator plate changes (OD selection added) to accomodate the Automatic Overdrive 700-R4 and the round automatic shift knob changes slightly with a raised detent button and a slight neck down on bottom.
