- Castrol’s TRANSMAX DUAL MULTIVEHICLE lubricant delivers smoother shifts for enhanced operational efficiency and longer component life
- Smooth Drive TechnologyTM features active control molecules that automatically adjust friction levels under changing pressures and speed for a smoother drive1
- Ideal ‘one fluid’ solution for workshops – suitable for almost all available wet dual-clutch transmissions2, including those used by Ford, VW Group, Nissan, BMW, and Mercedes-Benz
Castrol TRANSMAX DUAL MULTIVEHICLE
Castrol has launched TRANSMAX DUAL MULTIVEHICLE, a new, fully synthetic transmission fluid designed specifically for wet dual-clutch transmissions (DCTs). The new lubricant has been engineered to deliver smoother shifts for enhanced operational efficiency, as well as maximise the operational life of DCT components.
TRANSMAX DUAL MULTIVEHICLE is suitable for use in more than 90% of wet DCTs in the European car parc2, including most six- and seven-speed wet DCTs used in passenger vehicles manufactured by Ford, VW Group, Nissan, BMW, and Mercedes-Benz. This ‘one fluid’ solution helps to simplify the product selection and ordering process for solus and multi-marque workshops
On average, a modern automatic transmission can feature as many as 1,000 parts, with gear changes taking place up to 88,000 times a year during typical city driving3. This pressure can make transmissions work harder than ever before, with increased shudder, gear stiffness and component damage possible if the vehicle’s transmission fluid wears out or goes without the correct friction level4.
Castrol’s new TRANSMAX DUAL MULTIVEHICLE transmission fluid with Smooth Drive TechnologyTM features active control molecules that automatically adjust their management of friction under changing pressures and speed. This ensures the transmission is constantly served the right level of friction at any given moment, protecting the parts, and delivering a smoother drive for longer1.
The delivery of smooth shifts, longer component life and enhanced operational efficiency have all been confirmed following extensive analysis by Castrol’s technology experts. When testing TRANSMAX DUAL MULTIVEHICLE against another genuine oil, the new product provided smooth shifts more than two times longer, performing effectively at up to 17,000 cycles compared to just 7,500 for the genuine oil, at which point, shift shudder occurs1. Transmission bearings also exhibited 80% less wear5, along with a 50% less viscosity increase in oxidised oil6.
Simon Gurney, Technology Deployment Manager at Castrol said: “The mechanical demands placed on today’s wet dual clutch transmissions are more substantial than ever, so it’s vital that they can be protected against these pressures to avoid component failure. Following an extensive test and development process, Castrol TRANSMAX DUAL Multivehicle with Smooth Drive TechnologyTM offers unparalleled protection for the majority of DCTs in operation across Europe, providing workshops with a ready-made solution.”
Castrol TRANSMAX DUAL Multivehicle is the latest transmission fluid to join Castrol’s growing TRANSMAX product range, which includes TRANSMAX ATF, DUAL and CVT fluids for automatic transmissions. TRANSMAX MANUAL also ensures manual transmissions benefit from five times easier shifting at cold temperatures7. Today, two out of every three major vehicle manufacturers choose Castrol transmission fluids as part of their factory fill8.
