Lube Regulator & Converter Relief Spring Kit
Part No. 37000-01K

Fits '03-earlier units.

The converter regulator spring controls converter charge and feeds the lubrication circuit. When the spring becomes weak or broken, converter pressure is reduced. This causes delayed engagements, reduced torque output and increased operating temperatures.

The lube regulator spring affects converter pressure as well as lubrication pressure within the cooler and unit. When this spring breaks or becomes fatigued, converter temperature and gear train temperatures increase.

If either spring is excessively strong, both converter and cooler pressure increases. This can result in converter flex and cooler circuit cross leakage. The springs in Sonnax lube regulator and converter relieve spring kit 37000-01K have been calibrated to control converter charge and lube pressure.

  • Made from improved materials for increased durability over OE
  • Drop-in replacement
  • Converter spring is recalibrated to improve converter charge and internal pressure

These springs should be replaced as a pair, due to the pressure effects on each valve.

  • Lube Regulator Valve Spring 1.250"
  • Converter Relief Valve Spring 1.750"
