Sonnax GM 4L80E Actuator Feed Limit Valve Kit 4L80-E Automatic Transmission
OPT Product Code: SNX-34200-16K$65.68
Product Details
The OEM actuator feed limit (AFL) valve has a large reaction area and is greatly 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 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.
