Sonnax highlights its oversized cooler, main converter pressure and converter relief valve kit (#122740-10K) for Aisin Seiki AS66RC and AS69RC transmissions. The company says this kit can help avoid fluid loss that causes poor cooling, low cooler feed, low converter charge, TCC slip and TCC slip codes in these transmissions. Installing this kit re-establishes correct clearances for proper valve function, Sonnax says.
