Description

4L80E / 4L85E Lube Regulated Pressure Regulator Valve, Sonnax 34200-14K. 

The OE pressure regulator valve design prevents adequate cooler flow at low RPM and high pressure/demand conditions, which can create overheating. Additionally, in ’99-later vehicles, the factory EPC pressure was set high at idle, resulting in engine surge conditions in GM 4L80-E and 4L85-E units. Sonnax lube regulated pressure regulator valve 34200-14K 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. The 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
  • Drop-in Zip Valve parts install quickly and easily
