Why buy a new Tremec T-5 from Ford Racing? Because of what it will cost you in time and money to rebuild an existing one unless you're restoring a classic Fox-body Mustang. The beauty of a new World Class T-5 is convenience and reliability. Order one from Ford Racing or Summit Racing Equipment for under $1,400.

If you're going to rebuild an older T-5 transmission, look to D&D Performance in Detroit for most of the parts you'll need for a complete rebuild. At press time, a complete T-5 rebuild kit is $189. Hard and soft parts are also available.
** Ford also offered a 0.63:1 overdrive ratio in 1983.
The T-56 has the same number...
The T-56 has the same number of splines in and out as the classic Ford Top Loader - 10-spline in and 31-spline out.

It mandates the use of a cable clutch system, available from Modern Driveline. You can also use a hydraulic clutch system.

The Restomod Shop is going with a clutch pilot bearing for Project Reclaim T-56 six-speed. Although a pilot bushing is cheaper, the use of a bearing offers stability and longevity.
For Project Reclaim's T-56,...
For Project Reclaim's T-56, we're using the same dust cover or separator plate you would use with the T-5 or TKO. Only minor modifications are required to adapt this plate to a T-56.
We've enjoyed great success...
We've enjoyed great success using Centerforce Dual-Friction clutches in our project cars. The Dual Friction clutch holds tighter as engine rpm increases. This clutch disc is for a 10-spline input shaft, just like we would use with a Ford Top Loader.
It takes a couple of guys...
It takes a couple of guys to muscle a T-56 into place. The T-56 clears a classic Mustang's transmission tunnel with slight room to spare. However, it's tight under there. The only modification required is to the tunnel reinforcement, which must be trimmed to make room for the T-56. Ron Morris Performance has a new bolt-on T-56 crossmember for classic Mustangs.
