AFL Valve Sleeve Kit
Part No. 33886-01K

    Tooling:
  • 33886-TL
The OE actuator feed limit (AFL) valve regulates the oil pressure routed to the pressure control solenoid, each of the shift valves, and to the 1-2 signal and 2-3 signal circuits. Constant oscillation of this valve causes bore wear, reducing the AFL oil pressure, which can cause solenoid and ratio codes, clutch/band failure and harsh shifts. The Sonnax sleeve kit, 33886-01K, re-establishes the correct clearance with the OE valve.
  • Sleeve is made from highly wear-resistant aluminum.
  • Sleeve provides significantly more valve support to prevent wear.
  • Kit allows re-use of the OE valve.
  • Sleeve re-establishes the hydraulic integrity of the AFL circuit by restoring the correct clearance with the OE valve.

Always replace the O-rings on the pressure control solenoid and AFL filter O-rings while servicing this unit.
