Symptoms:

Severe wear of the boost sleeve due to continuous valve oscillation allows EPC and Reverse boost oil leakage.

Correction:
Install Sonnax O-ringed valve and sleeve to restore hydraulic integrity.


Vehicles with Ford E4OD and 4R100 transmissions frequently have problems with poor line rise and/or soft shifts. These complaints are often caused by severe wear of the pressure regulator boost sleeve, allowing EPC and Reverse boost oil leakage. The Sonnax boost valve kit eliminates these problems.

  • O-Rings provide additional protection against leakage at the sleeve bore
  • Sleeve manufactured from highly wear-resistant aluminum alloy
  • Hardcoat anodized aluminum valve combats premature wear
