Abstract
A multiplate torque converter clutch system, which is adapted for installation in torque converters of different automatic transmission manufacturers, namely, BORG WARNER, ALLISON, FORD, GENERAL MOTORS, and CHRYSLER transmissions. The present multiplate torque converter clutch system is provided in kit format including a hybrid lock-up piston/damper plate subassembly, multiple clutch plates including friction rings, a set of outer damper springs, and a set of inner damper springs. The present multiplate torque converter clutch system also includes a torque converter cover subassembly and a turbine hub subassembly configured to adapt the present torque converter clutch system to different vehicle engines and transmissions respectively. The hybrid lock-up piston/damper plate subassembly can be tuned to match a peak engine torque value by changing the number of damper springs. Advantageously, the present hybrid lock-up piston/damper plate subassembly is disassembled by removal of a single retaining ring to facilitate changes to the damper springs.
