Abstract:
1. A method of increasing fluid pressure within the torque converter apply circuit of an automatic transmission, wherein hydraulic pressure in said torque converter apply circuit is regulated by a replacement torque converter clutch regulator valve assembly disposed in a bore within the original equipment valve body of said transmission in fluid communication with said converter apply circuit and a line pressure circuit, said torque converter clutch regulator valve assembly responding to output pressure generated by a pulse width modulated solenoid circuit and further responding to a counteracting pressure from a balance apply circuit to control the flow of line pressure into said converter apply circuit, said method comprising the steps of: removing an original equipment torque converter clutch regulator valve assembly from said valve body; providing a replacement torque converter clutch regulator valve assembly including a replacement regulator apply valve, a regulator apply valve sleeve, and a replacement isolator valve; and installing said replacement torque converter clutch regulator valve assembly within said original equipment valve body.
