Product Description
8L45 8L90 Oversized Actuator Feed Limit Valve Kit by Sonnax
Part No. 154740-38K
Tooling: F-154740-TL38 VB-FIX
The actuator feed limit (AFL) valve in GM 8L45 and 8L90 transmissions functions to regulate the line pressure to other areas of the system, including the converter. When the pressure exceeds the limit set by the valve and spring, the valve moves to limit the fluid through the circuit to keep the pressure at the desired level.
Excessive wear in the AFL bore allows pressure loss and/or malfunctioning valve cycles that causes drivability concerns. The resulting low regulated pressure from leakage can cause low clutch pressure, transmission slips or harsh shifts.
Reconditioning the bore and installing the Sonnax oversized actuator feed limit valve kit 154740-38K restores proper hydraulic integrity of the circuit.
- Hardcoat anodized aluminum valve combats premature wear
- Oversized valve and replacement spring maintains OE functions and pressures
