Is your Ford truck or SUV shifting soft or slipping? This TransGo shift kit might be the fix – or better yet, a great upgrade! It's designed for Ford 5R55W, 5R55S, and 5R55N automatic transmissions found in 1999-2007 vehicles (like Explorers, Mountaineers, Rangers). Part number is SK 5R55W. Brand is TransGo, a trusted name in transmission performance. Fitment type is performance/custom – it firms up shifts for better durability and response. Made in the USA. Universal fitment is yes (for those specific transmissions). Mounting hardware is not included; you'll need basic tools. Manufacturer warranty length is unspecified. Comes brand new in original packaging. Not for beginners – you'll need some transmission knowledge to install this. But if you're tired of mushy shifts or want to prevent future failures, this kit is a solid investment. Take control of your transmission's feel!
