TH400 External High Flow Cooler Pressure Dump Kit

A converter pressure dump solenoid allows the transmission to bleed off the volume and pressure of the fluid going to the converter in which loosens the converter. We offer an internal and external dump to match up with your needs. Our external dump moves the most amount of fluid and is used on turbo cars for the starting line to help come up on the converter and the internal dump is used once the car leaves the line to help with traction. They can also be used on marginal track surfaces. These are just two of the ways to use these tuning aids. We recommend having both installed for the ultimate amount of tuning.
