  •  The OE pressure regulator valve design prevents adequate cooler flow at low RPM and high pressure/demand conditions, which can create overheat complaints. Additionally, in '99-later vehicles, the factory EPC pressure was set high at idle, resulting in engine surge conditions. The Sonnax line-to-lube pressure regulator valve provides a significant increase in cooler flow under low RPM and high pressure conditions that benefits all vehicles, and eliminates the need for reprogramming '99-later vehicles with high EPC pressure at idle.
  • Replacement pressure regulator valve has an encapsulated check valve that allows regulated flow to the converter charge/lube circuit at vehicle idle.
  • Check valve prevents converter or pump drainback.
  • Improves converter release pressure.
  • Prevents engine surge at idle in'99-later vehicles.
