Paddle shifters provide quick and responsive gear changes, allowing for more precise control over the transmission. This enhances the driving experience by enabling smoother and faster shifts, particularly in performance applications.
A flex plate connects the engine to the transmission, allowing for torque transfer. It is crucial to ensure the engine and transmission work together harmoniously, especially in high-performance applications.
These adapters allow you to retain a classic mechanical speedometer while using modern electronic signals from newer transmissions, combining the best of both worlds in terms of technology and aesthetics.
