Product Details

The Sonnax 77917-10 is a high-quality, heavy-duty pressure regulator valve spring designed for GM 4L60-E, 4L65-E, and 4L70-E automatic transmissions. This high-performance replacement spring is engineered to increase line pressure by approximately 13%, delivering improved transmission performance in both standard and high-performance applications.

Key Features:

  • Increases line pressure by approximately 13% over stock
  • High-performance spring construction for durability
  • Direct replacement for OE pressure regulator spring
  • Improves shift quality and clutch engagement
  • Machined from quality materials for long-lasting performance
  • Sold individually

Applications:

  • GM 4L60-E transmissions
  • GM 4L65-E transmissions
  • GM 4L70-E transmissions

This pressure regulator spring is ideal for transmission rebuilds where increased line pressure is desired to enhance performance and prevent clutch slippage. The higher spring rate helps maintain proper hydraulic pressure throughout the transmission's operating range, making it an excellent choice for both street and performance builds.

I was able to find the correct part and it was delivered in a timely manner!
