Abstract
A replacement torque converter clutch regulator valve assembly for an automatic transmission that controls clutch apply circuit pressure to the lockup piston within the torque converter clutch is disclosed. The present torque converter clutch regulator valve assembly includes an internal pressure relief valve that regulates clutch apply circuit pressure in the range of 90 to 100 pounds per square inch in comparison to the original equipment manufacture line pressure of 130 to 140 pounds per square inch thereby preventing deflection and malfunction of the lockup piston in operation. The present torque converter clutch regulator valve assembly also includes a modified switch valve having a fluid restricting baffle formed thereon that eliminates the initial spike in clutch apply circuit pressure at the start of each apply cycle to the torque converter clutch, which reduces shudder and provides improved control of the clutch apply and release circuits.
