Lock Up Clutch Control Plunger Valve Kit

LOCK UP CLUTCH CONTROL PLUNGER VALVE KIT

Symptoms:

  • TCC codes
  • TCC apply & release concerns
  • RPM surge on light acceleration
  • RPM surge on coas

Cause:
Bore wear at the lockup clutch control valve plunger sleeve results in loss of torque converter clutch control.

Correction:
Installing Sonnax lockup clutch control plunger valve kit restores proper clearances, allowing normal operation.


Converter-related complaints are common in the listed transmissions. Many times these complaints can be caused by wear at the plunger sleeve in the lockup clutch control valve bore. The plunger valve oscillates within the sleeve, responding to fluid pressure to help position the lockup clutch control valve for proper converter clutch apply. Excessive wear at the sleeve allows apply pressure to exhaust, resulting in a variety of TCC apply and release complaints. Installation of the Sonnax lockup clutch control plunger valve kit will restore hydraulic control of this circuit.

Kit contains:
  • Valve
  • Sleeve
