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
