2003 & Earlier, 6 solenoid 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.
- Made from improved materials for increased durability over OE
- Drop-in replacement
- Converter spring is recalibrated to improve converter charge and internal pressure
NOTE: These springs should be replaced as a pair, due to the pressure effects on each valve.
These springs work in ’03-earlier units only. These units can be identified by counting the solenoids: The earlier units have 6 solenoids. Do not use in ’04-later (7-solenoid) units.
