        • The Ford Racing Tremec TKO 600 Extra Heavy Duty 5-Speed Manual Transmission is designed for use in the 1979 to 1995 5.0L V8 Mustangs. As well as the 4.6 with the correct Bellhousing however at this time it has not been tested in an F-150.

        I understand that tremec tko600 comes in a Short input Shaft and a Long input Shaft , which one is this ? Or do you have the input Shaft length for this Ford Performance tranny? Thanks

        Will this fit into a 1988 Mustang gt? I have the bell housing from my stock t5 and I would also like to know if stock driveline would work length and spline wise. Also if another clutch other than stock would be necessary ? Thanks

        Is a unsprung clutch to much stress for this transmission, will the input shaft hold up to the abuse ?

        whats the difference in the .68 and .82?

        • The .82 will offer better acceleration in 5th, the .68 will offer decreased RPMs and fuel consumption in fifth gear.

            Best transmission

            I'm glad I went with this transmission. It holds the power of my hot 357w no problem and shifts smooth as butter.

            Obviously if u have a mustang then you know tremec tko is a great trans. So nothing but what I expected from that. BUT I'm beyond impressed with how fast I got this transmission. I've bought a lot of parts for my build from this site and will continue to do so.

            New edge Swap

            Swapped this trans in my new edge and couldn't be happier. Some say it doesn't shift great, but I can tell you it shifts great. After the break in period I really banged on it and WOW what a difference fron the t45..
