Symptoms:

  • Burnt clutches
  • Clutch failure
  • Shift concerns

Cause:

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.

Correction:

The tightly toleranced, drop-in replacement Sonnax valve and sleeve assembly restores proper hydraulic clearances and uses upgraded materials to prevent wear.
