Description

Sonnax Line Pressure Booster Kit for 4L60-E, 4L65-E, 4L70-E

The 4L60E-LB1 Line Pressure Booster Kit is expertly designed to fit early-style GM 4L60-E, 4L65-E, and 4L70-E pumps. Sonnax has engineered this kit with robust pressure regulator springs and large ratio boost valves. These components synergize to deliver progressive pressure increases, adapting seamlessly as driving conditions intensify.

Our pressure regulator springs are crafted to be approximately 10% stronger than OE springs, offering a more measured impact compared to other aftermarket options. The large ratio boost valves are designed to incrementally elevate pressure, precisely when it is most needed. This Sonnax kit harmoniously combines these springs and valves, yielding a subtle pressure boost at the low end and a high-end pressure that meets or exceeds other aftermarket kit springs.

Key Benefits:

  • Achieve crisper shifts and augmented torque capacity, without inducing low-speed harshness
  • Enhanced band and clutch holding capacity for superior transmission durability
  • Gradual pressure escalation as driving demands increase
  • Reap the rewards of elevated line pressure, without straining the pump at idle
  • Effortless installation with drop-in Zip Valve™ components

Note:

Replaces early-style boost valve with "long" 1.907" sleeve. For applications requiring a "short" 1.810" sleeve, use 4L60E-LB2. Refer to instructions for additional application details.

Kit Contents:

  • Pressure Regulator Spring
  • O-Rings (2)
  • Large Ratio Boost Assembly

Transmissions: 4L60E (M33,M30) 1993-UP, 4L65E (M32) 1993-UP, 4L70E (M70) 2004-UP
