Symptoms:

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

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.

Warning:

See valve comparison to determine which design casting is being worked on. TCC control plunger valves cannot be interchanged between 1st/2nd design valve bodies and 3rd/4th design valve bodies.

During converter clutch apply in Jatco/Nissan RE5R05A 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 63741-25K 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

For 1st and 2nd design TCC control plunger valve kit, use 63741-05K.

  • Sleeve
  • Valve .282" Dia.
