Oversized Actuator Feed Limit Valve
Part No. 144740-01

    Tooling:
  • 144740-TL
The function of the actuator feed limit (AFL) valve is to provide regulated pressure to shift solenoids. Wear in the AFL bore causes low clutch pressure and results in transmission slips/harsh shifts. This eventually leads to a loss of 4th through 6th Gears, and finally the loss of transmission function. Reconditioning the bore and installing Sonnax oversized AFL valve 144740-01 restores hydraulic control for revived shift operation in all ranges for 6T30/40/45/50 (Gen. 1 and 2) and 6T35/31/41/46/51 (Gen. 3 6T40) units.
  • Hardcoat anodized aluminum valve combats premature wear
  • Annular grooves help center valve in bore to reduce future side-load wear
