Product Description

Tremec 5-Speed Extra HD Transmission
Ensure your Mustang can handle all the power it's putting down with this Tremec TKO600 transmission! The M-7003-R58H is equipped with a 26 spline input shaft and a 31 spline output shaft. Designed to be a replacement of the earlier model TR-3550, the TKO has been significantly upgraded, making it more robust, flexible and versatile. The TKO600 is ideal for high-performance racing applications. The TKO 600 will require the (M-6392-R50) Ford Performance bellhousing, a (M-4841-A) Ford Performance 31 spline driveshaft yoke and a 10.5" clutch disc (M-7550-T302) that is designed for the use with a 26 spline input shaft. This is a perfect upgrade for any Fox Body Mustang, SN95 Mustang or New Edge Mustang!
