The 10R140 - The perfect gear ratio for any speed

The Ford 10R140 transmission is a powerhouse designed for heavy-duty Super Duty F-series trucks. It's a 10-speed automatic that can handle massive horsepower and torque, It is available with the 6.7 diesel boasting a rating of 475 hp and a staggering 1,050 ft-lbs of torque. With gear ratios ranging from 1st gear's 4.61:1 to 10th gear's 0.63:1, it's all about harnessing power efficiently. What's cool is that gears 8 through 10 are overdrive ratios, maximizing top speed while minimizing engine strain.

It is also available With the Godzilla 7.3. The Godzilla is Ford's 7.3-liter V8 engine for heavy-duty trucks, introduced in 2020. With an OHV, pushrod design in a V configuration, it's designed for high torque. Alongside the 6.2L Boss and 6.7L Power Stroke, it's Ford's biggest gasoline engine, perfect for heavy-duty tasks like the Super Duty series.

The transmission's innovation lies in its Lepelletier geartrain setup, using multiple inputs to create a variety of gear ratios. The engineering magic happens through its four planetary gear sets, making it possible to achieve 10 forward speeds by combining one or two inputs.

An interesting twist is the transmission fluid cooling system. Unlike the norm, it employs a coolant control valve attached to the coolant return hose to heat up the transmission fluid quickly, and later cools it down using coolant flow.

For enthusiasts, the Adaptive Learning Drive Cycle is key after any major work on the transmission, ensuring it adapts perfectly. This 10-speed beast is a vital player for monstrous trucks with even mightier power, and it's exciting to anticipate functionality, drivability and performance we will soon see from this platform.

The Guardian Converter

The Ford 10R140 transmission has proven to be a workhorse, this holds especially true when you compare it to its predecessors such as the 6R140 and the 5R110W. As reliable as the transmission can be under the most demanding driving situations the factory converter can begin to show signs of weakness. This is particularly apparent when it is exposed to higher torque loads when towing and hauling heavier loads. This will show it's head in the way of excessive heat and turbine slip. 

The Suncoast 10R140 torque converter sets out to alleviate those particular problems. This new 10R140 torque converter not only improves turbine slip but also improves the reliability of your transmission.

This converter is ideal for customers who are looking for an improvement over the factory 10R140 torque converter with a stock or slightly modified engine.
