A727 46RH 46RE TRANSMISSION Sonnax Billet Overdrive Rear Servo Piston 2.80"
Description: The rear servo piston in these Chrysler units can get wedged in the bore, causing bind in reverse. Intermittent binding leads to bore wear and band damage. This improved design 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.
