In listed Ford units, solenoid regulator valve affects the TCC solenoid feed with its modulated output. All TCC solenoid feed oil passes through this valve. When the solenoid regulator valve bore wears, valuable solenoid feed oil leaks to exhaust. When the solenoids are energized, this feed oil is directed to the bypass clutch control valve to apply the converter clutch. If there is excessive bore wear at the solenoid regulator valve, even though the solenoid is energized, there will be insufficient oil pressure to apply the converter clutch. Sonnax oversized solenoid regulator valve kit 96201-21K re-establishes the valve-to-bore fit, and prevents valuable solenoid feed oil leakage.
The solenoid regulator valve shares the same bore with the converter regulator valve. The converter regulator valve can cause problems with converter pressure, converter fill rate, cooler flow and EPC solenoid pressure. The Sonnax converter regulator valve 96201-23K can resolve these problems.
