With the continuous evolution of cars’ technology over the past years transmissions have become more complex, demanding more technologically advanced fluids to ensure they operate with efficiency and reliability. Using the right oil for your car is key to ensuring your transmission operates as designed and maintains its performance throughout the lifetime of the vehicle.
Castrol, with over 100 years of experience in developing transmission and axle fluids and being the choice of many leading car and transmissions manufacturers for factory-fill products, offers a complete range of products which can meet your car’s requirements.
The transmission is one of a vehicle’s most vital components, with almost 300/1000* finely engineered precision parts, making it one of the most complex and expensive units to repair or replace. Using the right oil and changing it at the right time is key to preventing transmission problems such as shudder, gear stiffness, axle whining or damaged parts before they occur.
Whether a car is automatic or manual, Castrol TRANSMAX range has the right transmission fluid for the vehicle, providing enhanced protection to all moving parts which enables longer transmission life.
