Pressure Regulator Valve 48RE OS

Pressure Regulator Valve 48RE OS • Pressure Regulator Valve • Line/TV Pressure Plug Assembly • Pressure Regulator Spring • Oversized pressure regulator valve is designed with an internal check valve that allows oil to flow into the converter charge circuit as soon as the vehicle is started. • Internal valve shuts down once line pressure reaches normal levels. • With engine off, the internal check valve prevents fluid from draining out through the orifice, reducing converter drainback. • Kit includes a matched oversized line/TV pressure plug and pressure regulator spring. Symptoms: • Converter drainback • Delayed engagement • Lube failures Cause: Poor converter line feed pressure caused by worn-out pressure regulator bores leads to delayed engagements and pump bushing and lube failure. Correction: The Sonnax steel valve kit offers increased stability while lube regulation improves converter feed at low RPM and high throttle conditions and allows bores to be oversized.
