Transmission Oils
A car transmission is one of the most important components of a vehicle. It’s what moves the power from the engine to the wheels.
It is differentiated between manual transmission, automatic transmission, double clutch transmissions, continuously variable transmissions, steering gear and hydraulic systems and between gears of cars and commercial vehicles. Choosing the right gear oil for the oil change or for the repair of the gearbox is crucial.
The most diverse additives are used to meet the most important requirements of each type of gearbox.
- Lubrication / wear protection
- "Synchro“-compatibility
- High friction stability
- Oxidation stability
- Excellent foaming and air release behavior
- High fuel-efficiency
- Good properties of shifting / low cold viscosity
- Corrosion protection
- High thermal stability
- Long drain intervals or even fill-for-life
- No noise, chatter damping
- High shear stability
- Compatibility with electric components/elements
- Loadcarrying capacity (EP = Extreme Pressure)
- Release contaminant and deposits
Gear Oil Types
Due to its special position as one of the leading lubricant developers and suppliers in the automotive industry, FUCHS offers the largest range of gear oils.
Manual Transmission Fluids (MTFs)
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 the quality of shifting is decisively influenced by the lubricant.
Automatic Transmission Fluids (ATF)
The coefficient of friction is important for the function of the automatic transmission when opening and closing the oil lubricated lamellar clutches and brakes in automatic transmissions. This is exactly what automatic transmission oils need to be exactly tuned to. Especially because of different requirements of certain manufacturers of automatic transmissions on the coefficient of friction characteristic no general classification has prevailed. OEM specifications are decisive for choosing the right automatic transmission oils.
Continuously Variable Transmissions Fluids (CVTF)
CVTFs are very similar to ATF oils, but in addition to the ATF properties, they are specially tailored to the friction properties required for contact between the metallic friction partners (variator to chain / transmission chains). Since CVT transmissions usually use strong hydraulic pumps, CVTFs must have particularly good foam properties and air release properties to prevent cavitation in the pump.
Double Clutch Transmission Fluids (DCTF)
Double clutch transmission fluids are the compromise between the characteristics of an outstanding MTF and a high-performance ATF. In addition, the use of hydraulic pumps increases the foam resistance requirements.
Drivetrain oils
Axle transmissions require particularly high wear protection (AW) and extreme pressure properties (EP). This is only possible with highly concentrated sulfur additives, which is why axle oils are not suitable for clutches or synchronization. In addition to high wear protection, axle drive oils must have good aging properties. Here, too, longer intervals between replacement and fill-for-life have to be achieved. With stricter directives and regulations concerning emmisions , the axle oils are getting more and more focussed for the efficiency optimization of the drivetrain.
Central Hydraulic / Power Steering Fluids
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 and covers the highest OEM quality standards and a wide application and approval profile.
Dedicated Hybrid Transmission Fluid (DHTF)
Transmissions in hybrid vehicles are capable of transmitting forces and torques transmitted by both internal combustion engines and electric motors to the drive axle. In addition to the tasks of a conventional dual-clutch transmission oil, the lubricant used in hybridized dual-clutch transmissions performs additional tasks in terms of e-motor compatibility.

RIGHT OIL, RIGHT APPLICATION
The transmission plays a vital role for a vehicle. The transmission fluid enables cooling and lubrication, helping transmit force and pressure and also preventing the unwanted build-up of harmful sludge or contaminates. Incorrect or dirty transmission fluid can lead to problems such as difficulties in gear shifting and in worst-case scenarios, total transmission failure.
