In GM 4L60-E, 4L65-E and 4L70-E units, the AFL valve is a solenoid feed regulator valve that feeds the EPC solenoid and shift solenoids. The OE AFL valve design has a large reaction area and is highly affected by side-loading, which wears the valve body bore. The EPC solenoid oscillates the torque signal and AFL oil, which increases valve action. As the bore wear increases, oil pressure is reduced to the shift solenoids, which causes solenoid and ratio codes. The same AFL oil loss results in lower line pressure. The improved Sonnax actuator feel limit valve kit 77754-09K eliminates these problems.

Hardcoat anodized aluminum valve combats premature wear
Valve has annular grooves to prevent side-loading and has 54% more support by operating in the full contact sleeve
