This TCI intermediate Kevlar band replaces the intermediate band in TH400 and 4L80E transmissions. As part of the TCI Powerband line, it uses Kevlar lining with a higher coefficient of friction for greater torque capacity and quicker, more positive band engagement. The bands are up to 18 percent wider than OE, and the anchor area uses extra thick, heat-treated, high-carbon steel to resist stretching and breakage. This band has no external band adjustment.
