Abstract:
A torque converter for an automatic transmission includes a first fluid flow path for supplying a fluid to a pump cavity, a second fluid flow path for removing the fluid from the pump cavity, and a third fluid flow path for supplying a hydraulic signal to a lock-up clutch. The third fluid flow path is separate and distinct from the first fluid flow path and the second fluid flow path. A sleeve divides a stepped axial bore in the turbine output shaft into an inner stepped axial bore cavity, which is part of the third fluid flow path, and an outer stepped axial bore cavity, which is part of the first fluid flow path. The torque converter further includes an isolator assembly having a twenty degree rotational travel dampening distance.
