While slippage in the torque converter is important under acceleration, this slippage becomes a liability once cruising speed is achieved. The lock-up clutch controls this slippage and creates a solid connection between the engine and transmission. If the load on the clutch is too much, slippage can occur leading to excessive heat and wear.

The RENNtech lock-up clutch upgrade uses a multi-element clutch upgrade with additional layer of friction material between the clutch plate, better friction material on the clutch face and a larger surface area of friction material to help control slippage. This allows for better heat management and increased holding power.
