At Black Shepherd Auto, we use only quality parts brands like Raybestos, Borg-Warner, Koyo, Motorcraft, and Sonnax in our builds. Our valve work, internal machining, and spring stiffness modifications provide dependable leak-free engagement with a near-factory shift feel.
All of our builds are 100% streetable. Everything we do here is to increase longevity and reliability, regardless of the horsepower rating. Internals are finish-machined during assembly to ensure our custom clearance requirements are met in every single unit. This is the ONLY way to have total control of the clearances due to every assembly having unique dimensional stackups.
All units are available in 2wd or 4wd configurations, 4r100 or E4OD, same price. Units built for v10 engines will retain their factory aluminum planet carriers. There is no option to upgrade aluminum planet carriers to steel for the gasoline transmissions.
Along with payment, an acceptable core is required at time of sale. See PURCHASING page for details.

Each of the units includes a specific torque converter custom built to match the performance level of the transmission. These are NOT mass-produced eBay torque converters, they are expertly hand-built the same way we build the transmissions.
