{"product_id":"3rd-4th-gear-manual-transmission-sleeve","title":"3rd\/4th Gear Manual Transmission Sleeve","description":"The Synchrotech SO-FC-3 is a manual transmission sleeve engineered to replace the stock component for the 3rd and 4th gears in specific Honda models. This part is designed to improve shifting performance and durability in the L15B engine's 6-speed transmission. It is a direct replacement for the factory 3-4 gear sleeve, intended for enthusiasts seeking to enhance their transmission's feel and longevity.\n\nThis Synchrotech sleeve is precision-manufactured for a precise fit and reliable operation. While the exact material composition is not detailed, Synchrotech is known for producing high-performance drivetrain components. The purpose of a synchro sleeve is to facilitate smooth and quick gear changes by synchronizing the speed of the gear and the shaft before engagement. An upgraded sleeve like the SO-FC-3 can help resolve issues like notchy shifting or difficulty engaging gears, especially under demanding driving conditions.\n\nThis specific sleeve is designed exclusively for the 2016-2020 Honda Civic Si and Civic EX-T Turbo models equipped with the L15B engine and the 6-speed manual transmission. Proper installation requires disassembly of the transmission, and it is recommended that this procedure be performed by a qualified technician or an individual with extensive manual transmission experience.","brand":"Synchrotech","offers":[{"title":"Default Title","offer_id":52663935107384,"sku":"SO-FC-3","price":115.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687721345.jpg?v=1784331014","url":"https:\/\/store.motormia.co\/products\/3rd-4th-gear-manual-transmission-sleeve","provider":"MOTORMIA","version":"1.0","type":"link"}
