TCC Control Plunger Valve Kit

Part No. 103740-01K

  • Valve
  • Sleeve

Complaint:

  • Burnt converter
  • Lockup shudder
  • Overheating
  • Poor fuel economy
  • TCC codes
  • TCC cycling

Cause:

Wear at the TCC control plunger valve sleeve allows converter apply oil leakage.


Correction:

Stop leakage and restore normal TCC operation by installing Sonnax TCC control plunger valve kit.

During converter clutch apply in listed transmissions, the TCC control plunger valve interacts with apply pressure to help cushion the stroking of the TCC control valve. Continuous valve oscillation causes sleeve deterioration, allowing critical apply pressure to escape the circuit. This can result in lockup shudder, overheating, premature or bumpy apply and TCC slippage as well as a burnt converter. Installing Sonnax TCC control plunger valve kit 103740-01K restores critical clearances and stops pressure loss for renewed TCC operation.

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