Product Details

The Sonnax 33886-01K is an actuator feed limit (AFL) valve sleeve kit designed for GM 4T40-E and 4T45-E automatic transmissions. The OE AFL valve regulates oil pressure routed to the pressure control solenoid, shift valves, and the 1-2 and 2-3 signal circuits.

Constant oscillation of the AFL valve causes bore wear, which reduces AFL oil pressure and can lead to solenoid and ratio codes, clutch and band failure, and harsh shifts. This Sonnax sleeve kit re-establishes the correct clearance with the OE valve, restoring proper hydraulic function and transmission performance.

Key Features:

  • Sleeve manufactured from highly wear-resistant aluminum
  • Provides significantly more valve support to prevent wear
  • Allows re-use of the original equipment valve
  • Restores hydraulic integrity of the AFL circuit by re-establishing correct clearance

Installation Note: Requires Sonnax tool kit 33886-TL for proper installation. Always replace the O-rings on the pressure control solenoid and AFL filter O-rings while servicing this unit.
