Product Details
The OEM pressure regulator valve design prevents adequate cooler flow at low RPM and high pressure/demand conditions, which can create overheat complaints. Additionally, in '99-up 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-up vehicles with high EPC pressure at idle. Features & Benefits: 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-up vehicles.
