Sonnax Toyota A540E Boost Valve and Sleeve Kit A540-E Lexus Automatic Transmission

Product Details


Large-Ratio Boost Sleeve and Large-Ratio Boost Valve. A severely worn boost sleeve in the A540E may allow TV pressure to leak into the reverse boost circuit during any valve body drive ranges. This oil is then open to exhaust through the manual valve, resulting in low line pressure. In reverse, reverse boost oil will leak past the worn sleeve and enter the TV circuit. This forces the pressure regulator valve into a higher than normal line pressure position. The Sonnax replacement boost valve and sleeve kit 89031-01K restores the proper clearances and hydraulic integrity. Features & Benefits: Sleeve is made from high-quality aluminum for better wear resistance. Valve is hard-coat anodized aluminum to prevent wear. Outperforms the OE parts.
