Shift Fork Piston Kit – Volvo Powershift

These shift fork pistons are part of the hydraulic control system in the Powershift transmission. They actuate the shift forks, allowing precise gear engagement under hydraulic pressure. Worn or damaged pistons and seals can lead to pressure loss, resulting in harsh shifting, stuck gears, or the transmission entering limp mode. Replacing them with a new kit restores proper hydraulic function and reliable gear changes.
