Symptoms:

  • Converter shudder & TCC slip
  • Damaged TCC linings
  • TCC codes
  • Overheated converter
  • Poor fuel economy

Cause:
Bore wear at the torque converter clutch valve allows crucial oil loss, resulting in TCC apply issues.

Correction:
Recover hydraulic control and renew TCC operation by reconditioning the bore and installing Sonnax oversized torque converter clutch valve kit.


ZF Valve name is WK-V
CHRYSLER Valve name is TCC-V

Vehicles equipped with Chrysler 845RE and ZF8HP45, ZF8HP55 and ZF8HP70 transmissions may experience converter shudder, TCC slip, overheating and/or damaged TCC linings, and may set various TCC-related trouble codes. These problems can be caused by wear in the torque converter clutch bore, which allows critical control fluid to escape the circuit. Reconditioning the bore and installing Sonnax oversized TCC valve kit prevents pressure loss and restores TCC operation by eliminating excess wear.
