Worn-out Aisin AWTF-80SC accumulator piston bores 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 linerise or clutch failure. The Sonnax accumulator piston and sleeve repair kit 39741-42K will restore a worn accumulator bore and correct leakage problems.

The accumulator bore and piston wear is severe enough that Sonnax accumulator piston kit [15741-14K] will not function in the worn bore.
