Accumulator Piston Kit

Partnr. 39741-42K

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.

• Salvages valve bodies with severe accumulator bore wear

• O-Ring seal improves piston response

The inner race or hub of the one-way roller clutch may come into contact with and cause wear to the back of the transmission case. This rearward movement of the hub is primarily a result of excessive endplay. To protect the case from further wear and eliminate excessive endplay, install a Sonnax case repair bearing, 22556-BRG. This repair bearing requires that the case be machined using a milling machine with a rotary table. Late cases will require machining of the reverse drum.
