Manual transmission problems in your 1999-04 Mustang are never fun to deal with. Lucky for you, Late Model Restoration has every part you need to get it fixed fast and right the first time. Our 5-speed and 6-speed transmissions from Ford Racing make the perfect replacement or upgrade to your Fox Body. When upgrading to an aftermarket transmission, you might need a matching aluminum or SFI approved bellhousing. Quick Time and Ford Racing offer different options to fit your application. While you have it all apart, now is a good time to replace your O.E.M. aluminum bearing retainer with a stronger steel retainer. The stock retainers can become worn down causing clutch engagement problems, so replacing now can save time and money later down the road. Want to shift quicker? Try a short throw shifter from Steeda, Ford, Pro 5.0, UPR, and SVE. Just need to refresh that transmission ? Overhaul it with Ford Racing's T-5 transmission rebuild kit. Top everything off with Royal Purple synthetic transmission fluid that improves shifting, lowers transmission temperatures, and reduces gear noise and make your driveline trouble free.
