Symptoms:

  • Harsh upshifts
  • Harsh downshifts
  • Gear ratio codes
  • Flare shifts
  • Solenoid performance codes

Cause:

As the control bores wear, the clutch apply and release rate are negatively affected. Apply will generally take longer and release occurs too quickly. This leads to a harsh, flare or bind shifts. The computer may code this as a gear ratio or solenoid mechanical issue.

Correction:

The Sonnax oversized clutch control valve kit with upgraded materials and minimal clearances prevents wear and restores proper hydraulic function.

Toyota/Lexus A760, A960 and AB60 series transmissions may exhibit poor shift quality due to wear in the clutch control bore. The clutch control valve controls clutch apply and release rates. The wear is typically visible upon inspection of the valve and bore. The Sonnax oversized clutch control valve kit 147741-14K allows the bore to be refurbished and the hydraulic integrity of the circuit to be restored.

  • Oversized, hard-coat anodized valve is manufactured to extremely tight tolerances and resist wear
  • Salvages previously non-repairable worn valve bodies and avoids expensive valve body replacement castings
  • Valve
  • End Plug
