While the Ford 6R140 transmission's line pressure range of 70 to 170 psi is perfect for stock truck usage, it is insufficient for heavy-duty and high horsepower applications. This isn't a problem for the BD Diesel 6R140 Auto Trans however, as it supplies up to 300 psi of line pressure in the transmission for an astounding 76% theoretical holding power.

This aftermarket solenoid replacement bypasses the transmission line pressure to maximize output and allowing the transmission to handle higher horsepower levels. The BD Diesel 6R140 Auto Trans only activates when the turbo boost exceeds 15 psi and does not generate excess heat when not in use nor cause clunky or awkward gear shifts. Prevent clutch slippage and premature clutch failure with the amazing holding power supplied by the BD Diesel 6R140 Auto Trans!

What sets BD Diesel Performance from other brands is that it is dedicated to providing regular and enthusiast diesel vehicle owners with competitive performance parts in both quality and price. The brand started in 1972 when Valley Fuel Injection Ltd. started offering services to the public.

Nowadays, Valley Fuel and BD Diesel Performance operate as one and direct over eight specialty divisions that serve specific vehicle applications: Fuel Injection Calibration Department, Exhaust Brake Manufacturing, Electronic Circuit Design and Assembly, Transmission and Torque Converter Design and Remanufacturing, Turbocharger Design, Installation, and Research and Development. All of these departments are housed in a 65,000 square foot high-tech facility manned by specialists and highly-trained individuals to ensure the manufacturing process is a seamless one.

Once BD Diesel Performance got its big break in the market after releasing the first exhaust brake for the then-flourishing pickup truck craze, the brand rode the wave of momentum and released a barrage of turbo, fuel, transmission, exhaust, and electronic solutions to give customers a wide range of options to choose from.
