Symptoms:

  • Shift concerns
  • Erratic shifts
  • Clutch failure

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 clutch apply control plunger valve kit restores proper hydraulic clearances and uses upgraded materials to prevent wear.

The noted Toyota transmissions may exhibit poor shift quality due to wear in the clutch apply control plunger sleeve. As the OE steel plunger valve oscillates in the cast aluminum bore, wear occurs. This prevents proper control of the inboard clutch apply control valve, resulting in problems with sequencing of clutch apply and release, which may cause flares and binds on up or downshifts. Ultimately this can lead to clutch failure.

Sonnax clutch apply control plunger valve kit 57917E-05K restores proper hydraulic clearances to ensure correct sequencing of clutch apply and release. Improved wear-resistant materials are used to provide durability and prevent future wear.
