Wako's Traction Booster Core 701 Inverter A/B Connector (1 piece)

In recent years, automatic transmissions (ATs) have been increasingly divided into two types: CVTs, which emphasize fuel efficiency, primarily found in compact and eco-friendly cars, and step ATs, which emphasize ride quality and driving performance, primarily found in large-displacement and sporty premium cars. However, even the latest ATs, which achieve both fuel efficiency and sportiness through multi-speed transmissions and precise lockup control, inevitably suffer from power loss in the torque converter (TC) and clutch due to their structure. CORE701 is the ultimate ATF additive, specifically designed to improve the driving feel of step ATs. Its double booster effect—a traction booster (improving TC efficiency) and a friction booster (improving clutch transmission efficiency)—provides powerful, smooth driving and quick gear changes. 1. Improved Traction Performance (Traction Booster) The traction coefficient of a fluid affects the efficiency of power transmission through a fluid. The graph on the right shows the change in traction coefficient that occurs when the speed between the two surfaces sandwiching the ATF is continuously changed. By adding a traction booster (the same amount as adding one bottle of CORE701 to 4L of ATF), it can be seen that the traction coefficient increases across the entire range. This means that more power can be transmitted, indicating improved torque converter efficiency. 2. Improves the friction coefficient (friction booster) The torque transmission capacity of a stepped automatic transmission vehicle depends on the friction characteristics of the built-in wet clutch. It has been confirmed that CORE701 improves torque transmission capacity over the long term by changing the friction characteristics of the ATF (raising the friction coefficient). ① Test method: Complies with JASO M348-2002 Automatic Transmission Fluid Friction Characteristics Test Method. ② Test conditions: Oil temperature 100°C, 5,000 cycles. ③ Evaluation method: The higher the static friction coefficient, the better the torque transmission efficiency. Improved torque transmission efficiency: The double booster effect of the traction booster and friction booster delivers powerful, smooth driving and quick gear changes. Improved torque converter efficiency: The traction booster improves the traction coefficient across the entire range, increasing torque converter efficiency. Improved clutch transmission efficiency: The friction booster improves torque transmission capacity over the long term, enhancing the driving feel of step automatic transmission vehicles. Ultimate performance as an ATF additive: Core 701 was developed as the ultimate ATF additive for the latest automatic transmissions. Wako's high quality: As a high-quality product, Wako's offers traction boosters that combine reliability and performance.
