{"product_id":"s5d310z-s5d320z-transmission-rebuild-kit","title":"S5D310Z S5D320Z Transmission Rebuild Kit","description":"The ZF RG-320Z-TRANS-KIT-BASIC is a transmission rebuild kit specifically engineered for the robust ZF S5D310Z and S5D320Z 5-speed transmissions. These transmissions were factory-equipped in popular BMW models such as the E36, E39, Z3, and E46, and are highly regarded for their power-handling capabilities, often chosen for engine swap projects. After considerable mileage, these transmissions may develop oil leaks or require a general refresh.\n\nThis basic rebuild kit provides the core components necessary to address common wear and tear, including the Input Shaft Seal, Selector Rod Seal, and Output Shaft Seal. Performing a transmission refresh is often done concurrently with other maintenance, such as installing a detent kit. For those seeking a more comprehensive overhaul, a Deluxe kit is also available, which includes additional items like the Foam Selector Rod Bushing, Pivot Fork Guide Tube, Pivot Fork, Pivot Pin, and Pivot Pin Spring. An upgraded stainless steel pivot pin is offered as an option with the deluxe kit.","brand":"ZF","offers":[{"title":"Default Title","offer_id":52866968355128,"sku":"RG-320Z-TRANS-KIT-BASIC","price":69.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687421888.webp?v=1787909991","url":"https:\/\/store.motormia.co\/products\/s5d310z-s5d320z-transmission-rebuild-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
