Airtex 2N1352 Automatic Transmission Pressure Regulator Spring

The Airtex 2N1352 is a replacement automatic transmission pressure regulator spring designed to restore proper hydraulic line pressure within the transmission valve body. The pressure regulator spring is a critical internal component that controls mainline fluid pressure, ensuring smooth, consistent gear engagement and preventing clutch pack slippage caused by inadequate pressure.

Airtex engineers this spring to OEM specifications, providing a direct-fit replacement that reinstates factory-calibrated line pressure without the need for additional modifications. Cross-references include OEM GM part number 29541896, Standard Motor Products TCS164 and TCS241.

Key Features:

• Engineered to OEM spring rate specifications for factory-level line pressure restoration
• Direct replacement for worn, fatigued, or broken pressure regulator springs
• Helps eliminate soft or erratic shifts caused by low line pressure
• Precision-manufactured for consistent performance and long service life
• Cross-references OEM GM part number 29541896

When a transmission pressure regulator spring weakens or breaks, the result is often low line pressure leading to slipping shifts, delayed engagement, or transmission overheating. Replacing this spring during a transmission overhaul or valve body service is a recommended preventive maintenance step to ensure reliable, long-term drivetrain performance.
