Symptoms:

  • Excess TCC slip
  • Low converter & lube flow
  • Low cooler flow
  • Overheating
  • Shudder
  • TCC apply & release concerns
  • TCC codes
  • TCC lining failure

Cause:

Excess wear at the TCC control valve bore due to continuous oscillation allows critical fluid loss that causes multiple TCC and lube/cooler circuit concerns.

Correction:

Salvage the pump and restore proper TCC apply/release and cooling circuit operation by installing Sonnax oversized TCC control valve kit.

Common concerns associated with Ford 6F35 units are high TCC slip, TCC lining degradation, TCC slip codes, and converter apply or release concerns. These issues are often caused by excess wear at the TCC control valve bore. In addition, converter/lube and cooler flow can be inhibited, resulting in an overheat situation. Reconditioning the bore and installing Sonnax oversized TCC control valve kit 144510-07K restores hydraulic integrity for renewed TCC, lubrication and cooler operation.

Proper TCC control relies on correct line pressure; if line pressure problems are discovered, Sonnax offers oversized pressure regulator valve kit 144510-03K.
