Symptoms:

  • High TCC apply pressure
  • TCC slip codes
  • Converter hub & stator damage
  • Brass contamination in oil pan

Cause:

The original converter regulator spring allows apply pressure to reach 180 psi in Drive, and allows release pressure to reach 225 psi in Reverse.

Correction:

Sonnax TCC regulator valve spring has less force, which reduces release pressure in Reverse, and regulates the apply pressure 150 psi in Drive.

The converter regulator valve spring controls converter apply pressure, which can go as high a 180 psi in Drive and 225 psi of release in Reverse at maximum line pressure in VW/Audi 01M, 01N and 01P units. This forces the converter turbine hub thrust washer to grind into the hub and stator. TCC slip codes also can result from excessive pressure. Sonnax TCC regulator valve spring 119940-19 is designed to exert less force, which reduces release pressure in Reverse and regulates the pressure to 150 in Drive.

  • Reduced force lowers regulated converter apply pressure to prevent parts damage and codes
