With all the equipment needed to rebuild torque converters (an investment of over $400,000), Team Ramco can make lockup converters that last. A factory clutch lining is 0.032 inch, while Ramco uses a high-carbon clutch that's 0.070-inch thick for added durability. This "bonder" is the machine that "glues" the lining on. Flashman considers lockup a must or the 3-4 clutches will take offense. There are several ways to achieve lockup, but without a computer only 2nd, 3rd, and 4th gears can be made lockable, or 4th gear only.
