Manual transmission problems in your 1979-1993 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 bell housing. 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.
