Manual transmission fluids
Explore our range of manual transmission fluids. Designed to help prolong component life and offer enhanced protection for commercial vehicles.
Transmission performance starts with the right fluid
In the demanding world of commercial transport, manual transmissions play a critical role – valued for their durability, driver control, and cost-efficiency. These systems must endure high torque loads, continuous gear engagement, and a wide range of environments – from congested city traffic to steep long-haul gradients. To maintain performance and extend service life, they rely on advanced lubricants engineered to help meet the demands of the task.
Our Castrol TRANSMAX range features advanced synthetic and mineral formulations – built to resist wear, reduce maintenance needs, and help extend transmission life. Keeping commercial vehicles on the road and performing efficiently.
Designed for durability
At Castrol, we understand the rigorous demands placed on manual transmissions across diverse commercial vehicle sectors. Castrol's range of advanced Manual Transmission Fluids (MTFs), including the Castrol TRANSMAX Manual line, is formulated to help combat these challenges head-on. It delivers performance and protection in the following areas:
Superior gear protection
Advanced Extreme Pressure (EP) additives form a durable protective layer on gear surfaces, preventing metal-to-metal contact, reducing wear, and resisting pitting under the harshest conditions.
Optimised shift quality
Friction modifiers ensure smooth, precise synchroniser engagement, enabling effortless gear shifts, improving drivability, and reducing driver fatigue.
Extended drain intervals
Designed to meet or exceed leading OEM specifications, Castrol MTFs support longer service intervals. Fewer oil changes and maintenance interventions can help reduce vehicle downtime and associated labour and service costs, contributing to a lower total cost of ownership for commercial fleets.
Thermal stability & heat dissipation
Our products are formulated to maintain viscosity and resist thermal breakdown during extended operation in high heat environments, whilst efficiently transferring heat away from critical components.
Oxidation, foam & corrosion resistance
Developed to resist oxidation and foaming during intense use, while providing protection against rust and corrosion – especially critical in demanding operating environments.
