Worn and leaking boost sleeves
These replacement boost valve kits provide more sealing area. Sleeves and valves made from high-quality hardened steel to prevent excessive wear.
Vehicles with 4T60 or 4T60-E transmissions often exhibit such problems as poor line rise, soft shifts, poor reverse boost, and/or 2nd and 3rd clutch distress. These problems can often be caused by worn and leaking boost sleeves. The OE boost valve spools have very narrow contact surfaces within the sleeves, which contribute to the leakage.
