Sonnax Lube Regulated Pressure Regulator Valves

4.9 out of 5 stars 20 Customer Reviews

The OE pressure regulator valve design prevents adequate cooler flow at low rpm and high-pressure conditions, which can create overheating. Additionally, in 1999 and 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 valves provide a significant increase in cooler flow under low rpm and high-pressure conditions that benefits all vehicles—and eliminates the need for reprogramming 1999 and later vehicles with high EPC pressure at idle.
