About This Product
This Colony transmission fill plug is a high-quality chrome replacement for 1980 to 1986 5-speed Big Twin models. It features the classic domed hex style that was standard on early five-speed gearboxes. The plug is 7/8"-18 threaded and comes equipped with an integrated dipstick, allowing you to easily check your transmission fluid levels. It serves as a direct replacement for OEM numbers 37071-79, used on 1980 to early 1985 models, and 37075-84, used on late 1985 to 1986 models. Whether you are replacing a rounded-off original or just want to add a bit of chrome to your driveline, this Colony plug offers the perfect blend of factory styling and durable finish.
Manufacturer part number: 8405-2.
