{"product_id":"tremec-tr-4050-5-speed-4wd-transmission","title":"TREMEC TR-4050 5-Speed 4WD Transmission","description":"The TREMEC TR-4050 5-Speed Manual Transmission (Part #TDET17341) is a robust 4WD gearbox designed for both rugged terrain and everyday driving needs. Engineered to handle a substantial 600 lb-ft of torque, it provides smooth and refined shifting suitable for rock crawling, towing, or daily commuting.\n\nOriginally equipped in Ford F-550 Super Duty trucks, the TR-4050 brings commercial-grade strength and proven reliability to the aftermarket. Its versatile gear ratios include an ultra-low 6.16 first gear for maximum torque multiplication and a fuel-saving 0.76 overdrive for highway efficiency, making it an excellent choice for off-road, overland, and utility vehicle applications.\n\nKey features of this transmission include all-synchronized gearing for smooth shifts (including reverse), a right-side 6-bolt PTO port for accessory pumps, and helical constant-mesh gears for reduced noise and increased strength. It also incorporates needle bearings under all gears for lower friction and heat, a die-cast aluminum case for durability and light weight, and advanced synchronizer technology for effortless shifting. The 5th gear synchronizer is located on the countershaft to improve Noise, Vibration, and Harshness (NVH) in overdrive, while the multi-rail internal linkage ensures a crisp and precise shift feel.\n\nSpecifications include a 1.125\" input shaft with a 10-spline count and 6.5\" length, a 0.590\" pilot diameter, and an overall length of 19.5\". The transmission weighs 164 lbs dry and features a 6.16 ratio for 1st gear, 3.11 for 2nd, 1.71 for 3rd, 1.00 for 4th, 0.76 for 5th (overdrive), and 6.03 for reverse. Silver Sport Transmissions also offers STX® short-throw shifter options and multiple 4WD conversion kits designed to support off-road builds, restomods, classic trucks, and custom applications.","brand":"American Powertrain","offers":[{"title":"Default Title","offer_id":52686912946488,"sku":"TDET17341","price":3295.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/661166103.webp?v=1784878341","url":"https:\/\/store.motormia.co\/products\/tremec-tr-4050-5-speed-4wd-transmission","provider":"MOTORMIA","version":"1.0","type":"link"}
