TCI's Max Shift High Pressure Transmission Cooler Cleaner & Flush eliminates metal shavings and sludge from new and rebuilt transmissions. The solution does not rely on gravity like other conventional transmission flushing devices. Instead, the cleaner fills the entire cooler and forces out metal shavings and other contaminants through the opposite direction in which they originally became lodged. Max Shift backflushes to prevent pollutants from become wedged deeper inside the cooler. It works with virtually any transmission cooler on the market today.
