Starting in 2005, Mustangs came equipped with the 5R55S transmission. Fully computerized, with five
speeds and a compact one piece design, this transmission has proven to be a tough little unit.

Performance Automatic has stepped it up a notch with some high performance tricks that make it even better.

High performance clutches and bands along with several hydraulic circuit modifications make the 5R55 a blast to drive.
