Sonnax Oversized Pressure Regulator Valve for GM Transmissions

The Sonnax Oversized Pressure Regulator Valve is a transmission rebuild upgrade for GM automatic transmissions. It is also known as a pressure regulator valve or main line pressure regulator. It is designed to restore proper line pressure control and to help correct the valve bore wear that causes pressure loss, slow or soft shifts, and premature clutch wear.

Key Features:

• Oversized valve design that compensates for worn pressure regulator valve bores in the valve body or pump
• Helps restore stable, consistent line pressure for firmer, more precise shifts
• Helps reduce internal fluid leakage that can cause low pressure and clutch slippage
• Made by Sonnax, a well-known name in aftermarket transmission rebuild technology
• Supports a more durable rebuild than a standard-size replacement part

A Sonnax oversized pressure regulator valve gives transmission rebuilders and technicians a reliable way to repair common wear-related pressure problems. Choose the specific variant for your transmission application from the options listed on this page.
