TCC CONTROL PLUNGER VALVE KIT (4R100)

TCC Control Plunger Valve Kit 4R100

TCC CONTROL PLUNGER VALVE KIT (4R100)

Fits PWM units only.

Symptoms:

  • Lockup shudder
  • TCC cycling

Cause:
Wear at the TCC control sleeve due to continuous plunger valve oscillation allows valuable oil leakage.

Correction:
This tightly toleranced replacement plunger valve kit restores hydraulic integrity for proper TCC control.


Ford 4R100 PWM units use a plunger valve assembly and coil spring to cushion the TCC control valve. That assembly uses regulated converter pressure as a variable hydraulic spring to control the rate of TCC apply. Continuous oscillation of the TCC control plunger valve wears the sleeve ID, allowing regulated converter pressure leakage. This can result in premature or bumpy TCC apply and/or shudder. The Sonnax TCC control plunger valve kit restores hydrualic integrity.

  • Sleeve is manufactured from highly wear-resistant aluminum alloy.
  • Hardcoat anodized aluminum valve combats premature wear.
