Car makers don't often collaborate on projects, especially when they're direct competitors. However, looming government fuel economy and emissions mandates can make strange bedfellows. And so, the Ford 10R80 10-speed automatic transmission was born. It was co-developed with General Motors, although Ford apparently took the engineering lead on the design. The mission was to create a 10 speed transmission that could improve both the fuel efficiency and performance of high-horsepower engines. The resulting 10L80 transmission was advanced enough to handle the power of the Ford Mustang GT 5.0 and Ford F150 Raptor, while improving the efficiency of the Ford Expedition and Lincoln Navigator.

Like it or not, a CVT transmission is one of the most efficient gearboxes ever invented. Because there are no actual gears, optimal engine speed can be continuously maintained depending on the load. This allows for seamless acceleration under hard throttle, and lower fuel consumption when you're just cruising. On a traditional geared transmission, a certain amount of energy gets lost every time a gear ratio is changed. This penalizes both fuel economy and performance, because the engine has to climb back to the RPMs it was just at. The Ford 10R80 10-speed transmission is designed to combine the efficiency benefits of a CVT, with the stepped feel of a traditional automatic transmission.

To create this optimal blend of performance and efficiency, the 10R80 transmission has a wide 7.39 gear ratio spread and a low 4.70 first gear for maximum performance off-the-line. Even though this Ford 10 speed automatic transmission has such a wide gear ratio, it has extremely small steps between the gears. This means the engine RPM only drops (approximately) 20% with each shift, which keeps the engine in the ideal RPM range to achieve either peak performance or efficiency (much like a CVT transmission). The Ford 10R80 also has three overdrive gears, which it can downshift from very quickly.

10R80 Transmission Gear Ratios

First – 4.70
Second – 2.99
Third – 2.15
Fourth – 1.80
Fifth – 1.52
Sixth – 1.28
Seventh – 1.00
Eighth – 0.85
Ninth – 0.69
Tenth – 0.64
Reverse – 4.87

As shown above this transmission offers a beautiful shift recovery in every gear which lends itself the perfect unit for narrow power bands. This allows the use of much larger camshafts in a naturally aspirated application. If you are looking into going to a forced induction setup this shift recovery allows for larger turbo and AR housing for max performance. 

This new torque converter comes with a billet stator with a variety of stall speeds available.
