Common problems associated with listed Ford transmissions are high TCC slip, TCC lining degradation, TCC slip codes and converter apply or release concerns. In addition, converter/lube and cooler flow can be inhibited, resulting in an overheat situation. These issues are often caused by excess wear at the TCC control valve bore. Reconditioning the bore and installing Sonnax oversized TCC control valve kit 124740-14K restores hydraulic integrity for proper TCC, lubrication and cooler operation. Hardcoat anodized aluminum valve combats premature wear.
