Symptoms:

  • Uncontrollable shift timing
  • Low line rise
  • Overheated clutch
  • Overheated band
  • TV pressure imbalance

Cause:

The throttle valve plug wears the sleeve, allowing throttle valve feed oil to leak past the plug and exhaust.

Correction:

Sonnax drop-in throttle valve plug kit has been designed to eliminate excess leakage and includes a tightly toleranced, wear-resistant sleeve.
