For greater durability and consistent performance in the Powerglide, TCI recommends their Dual Ring Servo Kit. This kit uses two stock PTFE sealing rings in place of the original design, which uses one. This doubles sealing effectiveness and prevents excessive leakage which can reduce band force. This feature also reduces vehicle rocking when the Trans-Brake is applied, and provides additional stability in lower gears. Perfect for the Super Class racer seeking positive Trans-Brake engagement when staging.
