Boostvalve TF60

Boostvalve TF60 Valve Sleeve This kit also fits BMW (6F21WA) & VW/Audi (09G, 09K, 09M). The boost sleeve in Aisin AW TF-60SN units wears from repeated oscillation of the boost valve, allowing Reverse pressure to exhaust. This will result in delayed Reverse, low line pressure in Reverse and/or burnt K3 and B2 brake clutches. Sonnax boost valve kit 15741-51K eliminates these concerns and restores proper hydraulic control. Symptoms: B2 Brake clutches burned Delayed Reverse K3 Clutch burned Low line rise in Reverse Cause: Continual boost valve stroking results in sleeve bore wear and loss of Reverse pressure. Correction: Installing Sonnax boost valve and sleeve restores critical tolerances to bring back normal operating conditions.
