OVERSIZE AFL VALVE KIT (6L45/50/80/90)
# 32781KA

Oversized Actuator Feed Limit Valve

OVERSIZE AFL VALVE KIT (6L45/50/80/90)

Tool Required


Symptoms:

  • Solenoid performance codes
  • Clutch failure
  • Wrong gear starts
  • Harsh shifts
  • Soft shifts

Cause:
Actuator feed limit bore wear causes erratic supply pressure to control solenoids.

Correction:
Recover hydraulic control and renew shift performance by reconditioning the bore and installing Sonnax oversized actuator feed limit valve.


GM 6L45, 6L50, 6L80 and 6L90 units often suffer from shift abnormalities caused by excess wear in the actuator feed limit (AFL) bore. This wear prevents proper regulation of oil pressure supplied to control solenoids, resulting in harsh or soft shifts, solenoid codes, wrong gear starts and clutch/band failure. Reconditioning the bore and installing this Sonnax oversized actuator feed limit valve renews the hydraulic integrity of this circuit, restoring normal shift operation and feel.

Proper AFL action depends on correct line pressure supply to the AFL valve.

  • Hardcoat anodized aluminum valve combats premature wear
  • Annular grooves help center valve in bore to reduce future side-load wear
