If you're rocking the stock transmission, you either have the C4 3-speed automatic or the SROD 4-speed manual. We offer plenty of direct-fit replacements designed to the factory specs to repair both of the stock transmission options. For those of you who want to experience improved performance and handling, a T5 5-speed manual transmission is a great choice. This popular swap converts the 1979 Mustang factory option to a 4-gear transmission with a fifth gear for overdrive, a popular performance upgrade for both 6-cylinder and small block V8 engines. If you'd like to add an overdrive gear but prefer an automatic, then an AOD conversion kit would be a perfect fit for you.

Whether you're looking to outperform the competition at drag events, or just want to keep your Fox moving, ACCELATEC, B&M, Ford Performance, and our other trusted vendors have the parts you need.
