Overflow Canister Pro X GM TH400 Trans

The Overflow Canister Pro X GM TH400 Trans from TCI is a specialized transmission cooling and fluid management system designed for General Motors TH400 three-speed automatic transmissions. This product is essential for high-performance and modified vehicles where increased driving demands can exceed the stock cooling capabilities.

The Overflow Canister Pro X features a pressurized reservoir that effectively captures and cools excess transmission fluid while maintaining optimal system pressure. This design helps prevent aeration, which is crucial in high-boost or high-horsepower applications where fluid agitation can lead to degradation. Its compact size and lightweight construction facilitate flexible installation in tight engine bays.

This canister is particularly beneficial for serious TH400 builders, restoration shops, and performance enthusiasts who require reliable fluid temperature control for improved shift quality and component longevity. It is engineered to work seamlessly with TH400 torque converters and internal cooling passages, ensuring efficient fluid recirculation without back pressure.
