SonnaxAccumulator Piston Kit

Wear at the accumulator bores or on the accumulator piston critical diameters in Toyota/Lexus listed units is very common. The C1 accumulator piston is used during apply of the C1 (Forward) clutch. Wear allows clutch apply oil to exhaust, resulting in harsh or delayed Forward engagements, burned C1 clutch, or slipping and flares in Forward gears. Sonnax C1 accumulator piston kit S47927K incorporates an O-ring for positive sealing, even in worn bores. O-Ring provides positive seal, even in worn bores; Annular grooves provide better piston centering and wear prevention; Hardcoat anodized aluminum piston combats premature wear; Drop-in Zip Valve™ parts install quickly and easily
