Required tool kit 33886-TL is no longer in production. Check with your distributor for availability.
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.
Always replace the O-rings on the pressure control solenoid and AFL filter O-rings while servicing this unit.
