It features clutch to clutch \nshifting which provides eight forward and one reverse gear. It also uses\n a four element lockup torque converter, four planetary gear sets as \nwell as five multiple disc and one mechanical clutch set. The 8L90 \nutilizes an off axis chain drive pump to maintain fluid volume and \noperating pressures. The externally located TCM controls the changing of\n gear ratios through the use of solenoids and also controls transmission\n line pressure through the use of a variable force motor. The TCM will \nalso control converter clutch operation. The 8L90 has undergone some \nparts changes from it’s inception until the present. Many of those \nchanges are indicated in this manual.The transmission in this manual was\n disassembled and reassembled without all factory tools.\u003c\/div\u003e","brand":"ATSG","offers":[{"title":"Default Title","offer_id":67766778069273,"sku":"334400A","price":44.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0718\/0288\/0281\/files\/57_fe4745da-939b-473c-8dcd-8aca6a7e93aa.jpg?v=1791798725","url":"https:\/\/automaxxparts.com\/products\/8l90-transmission-rebuild-book-atsg-techtran-manual-specs-and-procedures","provider":"MaxxIndustries","version":"1.0","type":"link"}
