This torque converter is for the 6L80E A6 six speed automatic transmission found in the 2006-2008 C6 Corvette. The torque converter is a 258 mm diameter which is over 40 mm smaller in diameter than the production 300 mm diameter torque converter. This significant reduction in diameter provides a noticeable difference in weight and inertia, providing for faster engine acceleration and throttle response.
The torque converter features a heavy duty twin plate torque converter clutch so despite the smaller diameter, it doesn't sacrifice torque converter clutch capacity. This torque converter works with the factory calibration with no changes required. These are brand new torque converters, not rebuilds or modified stock units.
