Wear allows solenoid feed pressure to exhaust resulting in various shift complaints and/or codes. The Sonnax accumulator piston incorporates an O-ring for positive sealing and annular grooves for better centering and wear prevention. • Drop-in replacement pistons no special tools required. • Pistons incorporate an o-ring for positive sealing, even on worn bores. • Annular grooves added for better piston centering and wear prevention. • Anodized aluminum piston prevents wear and eliminates thermal expansion related leakage.
