Key Features

• Faster Shifts

• Firmer Shifts

The Park Auto Motorsports TCU tune delivers quicker, more decisive gear changes. This is achieved by optimizing shift timing and increasing line pressure, which helps minimize clutch slip while boosting the transmission’s torque-handling capability. Higher line pressure allows the clutches to apply more firmly, improving grip and enabling the transmission to reliably handle increased power. Reduced slip combined with faster shifts can also contribute to improved transmission longevity. This upgrade is an excellent option for any supported vehicle, whether stock or modified.
