Anatomy of a Transmission: Oil Flow in the Pump-PR-Converter-Cooler Lube Circuits
Gregg Nader
Symptoms:
- Lockup shudder
- TCC cycling
Cause:
Wear at the TCC control sleeve due to continuous plunger valve oscillation allows valuable oil leakage.Correction:
Sonnax drop-in TCC control plunger valve kit is tightly toleranced to restore hydraulic integrity for proper TCC control.4R100
TCC Control Plunger Valve Kit
Part No. 36424-08K
Fits PWM units only.
View Instructions Find a DistributorFord 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 I.D., allowing regulated converter pressure leakage. This can result in premature or bumpy TCC apply and/or shudder. Sonnax TCC control plunger valve kit 36424-08K restores hydrualic integrity.
- Sleeve is manufactured from highly wear-resistant aluminum alloy
- Hardcoat anodized aluminum valve combats premature wear
- Drop-in Zip Valve™ parts install quickly and easily
Use of the Sonnax kit does not convert hydraulics to On-Off for use with single piston conversion. The PWM control is a function of the computer and TCC/PWM solenoid.
