About This Product
This Paughco transmission fill plug features a custom cap style with a high-quality chrome finish. It is designed without a dipstick, offering a clean and streamlined look for your gearbox. This plug is 7/8-18 threaded and is versatile enough to be used as a timing plug as well. It fits 1936 to 1986 4-speed OHV and Flathead Big Twin models, making it a great choice for Knucklehead, Panhead, and Shovelhead owners. It serves as a replacement for OEM 37072-79, 45830-48, and 2336-36. Whether you are finishing a custom build or replacing a weathered stock part, this Paughco plug provides a secure, leak-free fit.
