The BD Diesel Transmission Pressure Controller (1031320) is a performance-enhancing module designed specifically for 2011–2019 Ford Powerstroke trucks equipped with the 6R140 transmission. This controller helps improve transmission durability and shift performance by increasing the line pressure, especially under load or during towing. By optimizing hydraulic pressure, it reduces clutch slippage and heat buildup, which can significantly extend the life of the transmission. The Pressure Controller is plug-and-play, making for a straightforward installation without the need for custom tuning. Ideal for heavy-duty applications, it provides peace of mind for Powerstroke owners looking to protect their drivetrain while improving responsiveness and performance.
