Gear and transmission oils

In modern manual transmissions, in addition to classic wear reduction, the lubricant performs a wide variety of tasks and has an impact on ride comfort, as ease of gear shifting is decisively influenced by the lubricant.

Some transmission oils are specifically developed for a particular application, which means for example using one oil for the gearbox and one for the hypoid gear. There are also transmission oils designed for the entire drivetrain. The advantage is that the same oil can be used in the gearbox, the gear transfer case and the hypoid gear. Important characteristics in a transmission oil are that it must offer high wear protection and not age too quickly, despite high loads and temperatures. In gearboxes with synchronisers, the oil has to allow the right friction and be compatible with the material in the vanes. Here too, longer intervals between replacement and in some cases fill-for-life are available. With stricter directives and regulations concerning emissions, transmission oils are increasingly focused on optimising efficiency in the drivetrain. 

The coefficient of friction is important to the function of automatic transmissions when opening and closing disc clutches and brakes. This is exactly what ATFs need to be customised for. Especially because of the different requirements that manufacturers of automatic transmissions have on coefficient of friction properties, and there is no general classification. OEM specifications are crucial for automatic transmission fluids.

CVTFs are very similar to ATFs, but in addition to the ATF properties they are specially tailored to the friction properties required for contact between the metallic friction surfaces (variator to chain/transmission chains). Since CVT transmissions tend to use strong hydraulic pumps, CVTFs must have particularly good foam and air release properties to prevent cavitation in the pump.

DCTFs are a compromise between the characteristics of a high-quality MTF and a high-performance ATF. Also, the use of hydraulic pumps increases the foam resistance requirements.

Modern central hydraulic and power steering systems require special products to ensure best performance, durability and especially safety. The TITAN CHF range meets these requirements, while also covering the highest OEM quality standards and having a wide application and approval profile.
