This state-of-the-art friction material far exceeds OE material to withstand high stress, high temperatures and repeated cycling. Raybestos Powertrain GPZ friction plates greatly increase transmission performance and durability. This new SunCoast 10R80 rebuild kit comes with a new factory filter to ensure zero flow issues. When the oil is colder (higher viscosity) at startup, the fluid will flow through both the fine and course filter media.Īs the fluid heats up (less viscosity), the thermal plate will bend and restrict the coarse media section, directing most of the fluid through the fine media and, therefore, catching more of the finer debris once the fluid is heated giving it a far superior filtration system. There is a thermal plate inside the filter that separates the course and fine media. The course medium is common in most filters (orange filter paper), and the fine medium filtration (White paper) is the newer material. This 10R80 transmission has a newly designed filter that has two types of media, fine and course (medium). Newly Designed Thermal Flow Control Filter 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 allows the use of much larger camshafts in a naturally aspirated application. The Ford 10R80 also has three overdrive gears, which it can downshift from very quick 10R80 Transmission Gear Ratios First – 4.70Īs shown above, this transmission offers a beautiful shift recovery in every gear which lends itself the perfect unit for narrow power bands. 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). Even though this Ford 10-speed automatic transmission has such a wide gear ratio, it has extremely small steps between the gears. 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. 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. This penalizes both fuel economy and performance because the engine has to climb back to the RPMs it was just at. On a traditional geared transmission, a certain amount of energy gets lost every time a gear ratio is changed. This allows for seamless acceleration under hard throttle and lower fuel consumption when you’re just cruising. Because there are no actual gears, optimal engine speed can be continuously maintained depending on the load.
Like it or not, a CVT transmission is one of the most efficient gearboxes ever invented. The resulting Ford 10R80 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. The mission was to create a 10-speed transmission that could improve both the fuel efficiency and performance of high-horsepower engines. It was co-developed with General Motors, although Ford apparently took the engineering lead on the design. And so, the Ford 10R80 10-speed automatic transmission was born. However, looming government fuel economy and emissions mandates can make strange bedfellows. Car makers don’t often collaborate on projects, especially when they’re direct competitors.
