A replacement torque converter clutch regulator valve assembly for use within an automatic transmission including two cooperating valves, namely a regulator apply valve and an isolator valve, disposed in fluid communication with a line pressure circuit and a torque converter clutch apply circuit is disclosed. In one embodiment the regulator apply valve employs a regulator apply valve sleeve, which provides support to the regulator apply valve to prevent side loading. Modified control lands on the regulator apply valve have a reduced cross-sectional area calculated to increase the influence of the pulse width modulated solenoid, which provides an output pressure in response to the duty cycle imposed on the solenoid coil in pulse width modulated converter systems. In an alternative embodiment an isolator valve sleeve is utilized for instances wherein the isolator valve bore has extreme wear that cannot be corrected solely by the installation of the replacement isolator valve.
