{"product_id":"tremec-tkx-5-speed-transmission-kit","title":"Tremec TKX 5-Speed Transmission Kit","description":"The American Powertrain ProFit TKX transmission kit is engineered for 1970-1974 GM F-Body vehicles, offering a robust solution for upgrading from a 4-speed manual.\n\nThis 5-speed transmission boasts a 600 ft-lb constant load rating, constructed with 4616 chromoly gears and shafts for durability. It features a 26-spline input shaft and a 31-spline output shaft, with a .68 OD for efficient highway cruising. The transmission is designed for both electronic and mechanical speedometers and fits any GM 4-speed bell housing.\n\nThe included ProFit installation kit streamlines the conversion process. Key components are the X-Factor modular aluminum crossmember, certified to 1000hp with 3.5-inch exhaust clearance, and the AP Revolution Offset Shifter Mechanism, designed to maintain the OE 4-speed shift position. A 1330 solid yoke, mechanical speedometer conversion adapter, VSS wiring harness, and an ISO-X ballistic mount are also part of the comprehensive kit, along with a white shift knob.\n\nThis kit requires a 26-spline clutch disc, which is not included. While the main transmission is rated for 600 ft-lbs of torque, an optional TKO Extreme upgrade is available, increasing the rating to 950 ft-lbs with the addition of Cryo treatment and other internal enhancements for high-torque applications.","brand":"American Powertrain","offers":[{"title":"Default Title","offer_id":52686913208632,"sku":"APO-COGM-F2FX","price":4199.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660182255.jpg?v=1784878345","url":"https:\/\/store.motormia.co\/products\/tremec-tkx-5-speed-transmission-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
