The BD RoadMaster transmission is significantly more durable than a stock unit because it corrects known factory flaws instead of just replacing parts. It features a modified valve body for 30% higher line pressure, an improved CDF drum to prevent failures, and a deep pan that adds 2 quarts of fluid capacity for better cooling. — While a stock replacement just resets the clock on potential factory issues, the BD RoadMaster is re-engineered for longevity and improved performance. The key improvements include: — • Increased Clutch Holding: A new valve body is modified to increase line pressure by approximately 30%, providing firmer clutch application to prevent slippage. • CDF Drum Fix: Includes a revised CDF drum with a retaining feature to permanently solve the common sleeve failure that causes pressure loss and burnt clutches. • Enhanced Cooling: Comes with a deep sump transmission pan that holds an extra 2 quarts of fluid, helping dissipate heat and extend the life of the fluid and internal components. • Upgraded Converter: The included ProForce torque converter uses new, more durable friction material to prevent premature wear and shudder. • New Internals: The build utilizes brand new OEM clutches and steels, ensuring a fresh start with top-tier components.
