Symptoms:

  • TCC codes
  • TCC apply & release concerns
  • TCC slip
  • TCC surge
  • Overheated fluid, bushings & converter

Cause:

Bore wear at the spring end of the valve allows the SLT circuit and regulated converter pressure to cross leak. Bore wear at the balance end of the valve reduces converter and lube flow.

Correction:

Sonnax secondary pressure regulator valve kit allows the hydraulic integrity of the bore to be restored after reaming. With the improved materials and valve support, the service life can be extended beyond the OE casting.
