- Burnt clutches
- Clutch failure
- Shift concerns
Continuous oscillation of the steel clutch apply control plunger valve wears the cast-aluminum sleeve bore, allowing clutch apply pressure to exhaust and preventing proper control of the clutch apply control valve.
The tightly toleranced, drop-in replacement Sonnax valve and sleeve assembly restores proper hydraulic clearances and uses upgraded materials to prevent wear.

- The Sonnax sleeve is manufactured from highly wear-resistant billet aluminum.
- The Sonnax valve has been manufactured from hard-coat anodized aluminum to prevent wear.
- Annular grooves have been added to the valve to prevent sideloading related wear.
