sonnax accumulator piston kit, aisin aw, aw tf-60sn, tf-80/81sc, tr-60sn, each

Worn-out accumulator piston bores in listed Aisin AW 6-speed units allow pressurized transmission fluid to leak past the accumulator piston to the sump. These leaks can result in a flare at upshift, delayed engagement, poor line rise or clutch failure. The Sonnax accumulator piston kit 39741-42K will restore a worn accumulator bore and correct leakage problems.
