    Description

    A727 46RH 46RE Automatic Transmission
    Billet Aluminum Reverse Servo Piston
    Symptoms this piston addresses:
    Burnt bands
    No Reverse
    Rear servo piston sticking/breakage
    Cause:
    Piston cocking in bore and pin bore wear inhibits band apply.
    Correction:
    Restore normal servo operation by installing Sonnax rear servo piston.
    The rear servo piston in Chrysler 46RH/RE and A727 units can get wedged in the bore, causing bind in Reverse. Intermittent binding leads to bore wear and band damage. The improved design and material of Sonnax rear servo piston 22912 eliminates these concerns for consistent rear band apply.
    Modified seal ridges prevent piston from sticking in case bore
    Billet aluminum won’t crack like OE cast piston
    2.80" O.D. piston
