Sonnax 122740-01K, AS66RC / AS69RC B1/B2 Apply Control Plunger Valve Kit

A worn B1 or B2 apply control plunger valve sleeve in the Aisin Seiki AS66RC and AS69RC transmissions can cause shift flares, delayed or harsh engagements, low line pressure and burnt B1 and B2 clutches. Additionally, the system routes the line pressure to the B1 and B2 plunger valve to aid in proper apply control clutches.

If the sleeve is worn at the B1 location, line pressure exhausts which will result in 1-2 and 5-6 shift flares, low line pressure and a burned B1 clutch. Furthermore, if the sleeve is worn at the B1 location, line pressure exhausts which will result in 1-2 and 5-6 shift flares, low line pressure, and a burned B1 clutch. Consequently, this results in delayed or harsh forward and reverse engagements, as well as a burned B2 clutch.

Also, Sonnax B1/B2 apply control plunger valve kit 122740-01K restores hydraulic control at either location to address these issues.
