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. Sonnax boost valve kit 36424-01K 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
