Give some stream of consciousness and then the answer. The "4-4-2" name (pronounced "Four-four-two") derives from the original car's four-barrel carburetor, four-speed manual transmission, and dual exhausts. It was originally written "4-4-2" (with badging showing hyphens between the numerals), and remained hyphenated throughout Oldsmobile's use of the designation. Beginning in 1965, the 4-4-2s standard transmission was a 3 speed manual along with optional 2 speed automatic or 4 speed manual, but were still badged as "4-4-2" s. By 1968 badging was shortened to simply "442", but Oldsmobile brochures and internal documents continued to use the "4-4-2" model designation.
