At Black Shepherd Auto, we use only quality parts brands like Raybestos, Borg-Warner, Koyo, Motorcraft, and Sonnax in our builds. Our valve, clutch pack clearance, and spring stiffness modifications provide a factory-like shift feel for our Daily/Tow unit, up to what we believe is the best compromise between a factory-like shift feel and the quickness required by higher horsepower loads to keep slippage and oil temps as low as possible in the Street and Super Street units.
All of our builds are 100% streetable and retain the factory TCC lockup mode. Everything we do here is to increase longevity and reliability, regardless of the horsepower rating. You will not be able to "Chirp 2nd" with any of our units, and that is on purpose!
All units are available in 2wd or 4wd configurations, 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 a v10 unit.
Along with payment, an acceptable core is required at time of sale. See PURCHASING page for details.
This is our most popular unit. This transmission is great for a daily driver, plowing, towing, working trucks, and anyone who just wants a reliable unit that will outlast any stock or factory build. This transmission will shift like new, but will have a tremendous increase in reliability, longevity, and power handling.
This unit includes the following:
The Street unit includes the following:
The Super Street unit includes the following:
This is the Daily/Tow model for PTO trucks.
NOTE: A good rebuildable coast drum is required and is part of PTO core inspection. PTO parts are very expensive and rare. A PTO core with a damaged coast drum assembly will incur an additional significant replacement charge. If you suspect your coast drum is broken, make it known ASAP.
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.
Just as with the transmissions, an acceptable core is required with purchase.
